Here are a few Scriptures about those who Sanctify themselves and those sanctified by YHWH;
Isaiah 66:17, those who sanctify themselves and cleanse themselves at the gardens after ‘one’ in the midst, eating flesh of pigs and the abomination and the mouse, are snatched away, together,” declares יהוה.
Isa 65:4, "who sit among the burial-sites, and spend the night in secret places, who eat flesh of pigs,a and the broth of unclean meat is in their pots.
Ezekiel 20:12, "Moreover, I also gave them My Sabbaths, to be a *sign between Me and them, that they might know that I am YHWH Who sanctifies them."
*Sign is Word #H226, Hebrew Dictionary, Strong's Exhaustive Concordance, meaning mark, token, sign, consent, flag, evidence of consent.
This is the same Hebrew word (owth) from Exodus 13:9, this time it is used speaking of a specific Law; the Sabbath and is called the sign/mark/evidence of consent. Also notice how YHWH says, “I am YHWH Who sanctifies them.” If I choose my own way I “sanctify myself” if I choose His way “He sanctifies me.” The following passage shows an example of those who “sanctify themselves” and if we consider the context of time frame, it is end times, shown by the return of YHWH when He will make judgment;
Isaiah 66:15-24, For, behold, יהוה will come with fire, and with his chariots like a whirlwind, to render his anger with fury, and his rebuke with flames of fire. 16, For by fire and by his sword will יהוה plead with all flesh: and the slain of יהוה shall be many. 17, They that sanctify themselves, and purify themselves in the gardens behind one in the center (H310 אַחַר 'achar - H259 אֶחָד 'echad - H8432 תָּוֶךְ tavek, meaning followingbehind one in the centerof a congregation), eating swine's flesh, and the abomination, and the mouse, shall be consumed together, saith יהוה. 18, For I know their works and their thoughts: it shall come, that I will gather all nations and tongues; and they shall come, and see my glory. 19, And I will set a sign among them, and I will send those that escape of them unto the nations, to Tarshish, Pul, and Lud, that draw the bow, to Tubal, and Javan, to the isles afar off, that have not heard my fame, neither have seen my glory; and they shall declare my glory among the Gentiles. 20, And they shall bring all your brethren for an offering unto יהוה out of all nations upon horses, and in chariots, and in litters, and upon mules, and upon swift beasts, to my holy mountain Jerusalem, saith יהוה, as the children of Israel bring an offering in a clean vessel into the house of יהוה. 21, And I will also take of them for priests and for Levites, saith יהוה. 22, For as the new heavens and the new earth, which I will make, shall remain before me, saith יהוה, so shall your seed and your name remain. 23, And it shall come to pass, that from one new moon to another, and from one Sabbath to another, shall all flesh come to worship before me, saith יהוה. 24, And they shall go forth, and look upon the carcasses of the men that have transgressed against me: for their worm shall not die, neither shall their fire be quenched; and they shall be an abhorring unto all flesh."
