The Sabbath is a sign between GOD and his children.
Exo 31:12 And the LORD spake unto Moses, saying, (KJV)
Exo 31:13 Speak thou also unto the children of Israel, saying, Verily my sabbaths ye shall keep:
for it isa sign between me and you throughout your generations; that ye may know that I am the LORD that doth sanctify you.
Exo 31:14 Ye shall keep the sabbath therefore; for it is holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth
any work therein, that soul shall be cut off from among his people.
Exo 31:15 Six days may work be done;
but in the seventh is the sabbath of rest, holy to the LORD: whosoever doeth
any work in the sabbath day, he shall surely be put to death.
Exo 31:16 Wherefore the children of Israel shall keep the sabbath, t
o observe the sabbath throughout their generations, for a perpetual covenant.
Exo 31:17 It is a sign between me and the children of Israel for ever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed.
Exo 31:18 And he gave unto Moses, when he had made an end of communing with him upon mount Sinai, two tables of testimony, tables of stone,
written with the finger of God.
I do not explain well but these commentaries below do help to understand;
Pulpit Commentary ( source bible hub )
Verse 13. - Verily. Rosenmuller suggests, "Nevertheless." But there is no need for any change. It is a sign. Hitherto circumcision had been the only visible "sign" that the Israelites were under a special covenant with God - his people, bound to him by special ties (
Genesis 17:9-14;
Acts 7:8). The adoption of circumcision by the Egyptians and other nations (Herod. 2:104) had produced the effect that this "sign" was no longer distinguishing. It might be still" a sign of profession "; but it had ceased to be "a mark of difference "; and some other mark was therefore needed. Such the observance of the sabbath by entire abstinence from servile work became. No other nation adopted it. It continued to Roman times the mark and badge of a Jew.(Juv. Sat. 6:159; 14:96). That ye may know, etc. By keeping the sabbath day as a day of holy rest the Israelites would know - i.e., would realise severally in their own per sons, that God was their sanctifier. Sanctification would be the fruit of their obedience. Exodus 31:13
Excerpt of Matthew Poole's Commentary ( source bible hub )
My sabbaths ye shall keep: this precept is here repeated, either,
1. To show the chief use of the tabernacle, and all this cost and trouble about it, to wit, that they might there acceptably serve God, as in some measure upon every day, so especially upon the sabbath day. Or rather,
2. To restrain the time for the doing of the forementioned works: q.d. Though the work of the tabernacle and utensils be holy, and for a holy use, yet I will not have it done upon my holy day. The sabbath was not made for them, but they for it, and therefore they shall give place to it.
It is a sign between me and you. The sabbath is a fivefold sign:
1. Commemorative, of God’s creation of and dominion over them and all other things, to whom they do hereby profess their subjection.
2. Indicative, showing that they were made to be holy, and that their sanctification can be had from none but from God, as it here follows, and from the observation of God’s days and appointments.
3. Distinctive, whereby they owned themselves to be the Lord’s peculiar people, by a religious keeping of those sabbaths, which the rest of the world grossly neglected and profanely scoffed at.
4. Prefigurative, of that rest which Christ should purchase for them, to wit, a rest from the burden of the ceremonial, and from the curses and rigours of the moral law, as also from sin and the wrath of God for ever. See Heb 4.
5. Confirmative, both assuring them of God’s good will to them, and that as he blessed the sabbath for their sakes, so he would bless them in the holy use of it with temporal, spiritual, and everlasting blessings, as he declares in many places of Scripture; and assuring God of their standing to that covenant made between God and them. So that this was a mutual stipulation or ratification of the covenant of grace on both sides.
That doth sanctify you; that selecteth you out of all people, and consecrateth you to myself, and to my service and worship, a great part whereof is the observation of the sabbath. Or, that sanctifieth you by my word and ordinances, which are in more eminent and solemn manner dispensed upon the sabbath day, by the observation whereof you declare that you own me as your only Sanctifier; and so we may observe, the sabbath owns the Lord as our Creator, and as our Redeemer, and as our Sanctifier; and therefore it is no wonder God so severely enjoins the sanctification of the sabbath, and punisheth the neglect of it, it being a tacit renouncing or disowning of God the Father, the Son, and the Holy Ghost.
The fact that Peter appointed by GOD to be sent to preach to the gentiles (ACTS 15:7) is proof that the commandments were also preached to the gentiles and are not only for Israel;
Mat 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
Mat 28:20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
Benson Commentary ( cource Biblehub )
Matthew 28:20. Teaching them to observe all things, &c. — Here we have, 1st, The duty of the apostles and ministers of Christ, which is,
to teach his disciples to observe all things that he has commanded; that is, they must instruct them in all the doctrines and precepts taught by Christ, and inculcate upon them the necessity of understanding and believing the former, and obeying the latter; and must assist them in applying Christ’s general commands to particular cases. They must teach them, not their own or any man’s fancies and inventions, but the truths and institutions of Christ; to them they must religiously adhere, and in the knowledge of them must train up his followers.
As Christ does not here command any thing to be taught which he himself had not taught, we may infer that every thing fundamental and essential to salvation may be found in the gospels, and that even the apostles themselves had not a right to teach any thing as necessary to salvation which Christ himself had not asserted to be Song of Solomon 2 d, The duty of Christ’s disciples, of all that are dedicated to him in baptism; they must observe all things whatsoever that he has commanded, and in order thereto, must submit to the teaching of those whom he sends. Our admission into the visible church is in order to something further; namely, our being prepared for and employed in his service. By our baptism we are obliged, 1st, To make the doctrines of Christ the rule of our faith, and his commands the directory of our practice. We are under the law to Christ, and must obey, and in all our obedience must have an eye to the command, and do what we do as unto the Lord.
Peace be upon you all.
