Yes, true
and
"'You shall not crossbreed different kinds of animals. "'you shall not sow your field with two kinds of seed; "'neither shall there come upon on you a garment made of two kinds of material.
and
Leviticus 15: 22. Whoever touches anything that she sits on shall wash his clothes, and bathe himself in water, and be unclean until the evening. 23. If it is on the bed, or on anything whereon she sits, when he touches it, he shall be unclean until the evening.

Matt. 13:13 Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.
14 And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive:
15
For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.
The Bible teaches that it's Word's are Spiritual, and that the understanding of it's Word's is a Spiritual understanding which is either granted or withheld by Jesus.
Jesus explains, for those who truly Seek Him, how to be granted this understanding.
John 14:15 If ye love me, keep my commandments.16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
A child is not expected to run the 440 at birth. It must first learn how to rollover, then to crawl, then walk, then run. It's a process that must be learned.
It can not eat a steak at birth. It must first to suckle, then the bottle, then it must grow teeth and learn to chew and so on. It is a process.
Luke 18:16 But Jesus called them unto him, and said, Suffer little children to come unto me, and forbid them not: for of such is the kingdom of God.
17
Verily I say unto you, Whosoever shall not receive the kingdom of God as a little child shall in no wise enter therein.
There are things a young Christian can understand. Instructions that are easy to follow. We have the milk first.
1 Pet. 2:1 Wherefore laying aside all malice, and all guile, and hypocrisies, and envies, and all evil speakings,
2 As newborn babes, desire the sincere milk of the word, that ye may grow thereby:
1 Cor. 3:1 And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ.
2 I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able.
And as we grow we are able to understand more Spiritual aspects His Word. It seems God thinks that if a person will not submit themselves to the simple things that even a child can do, why waste His time on showing them more "adult" aspects of His Word.
The scriptures you posted have a perfectly sound spiritual meaning which are pertinent to the lives of a Christian. You don't know or understand them because God, for His own reasons, has not revealed them to you. If you are following His Sayings and instructions He is faithful to do as He promised. But just because you don't understand the lesson, doesn't mean the teacher is at fault.
And remember, Jesus learned the same way.
Heb. 5:8 Though he were a Son, yet learned he obedience by the things which he suffered;
9 And being made perfect, he became the author of eternal salvation unto all them that obey him;
10 Called of God an high priest after the order of Melchisedec.
11 Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing.
12 For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.
13 For every one that useth milk is unskilful in the word of righteousness: for he is a babe.
14 But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil.
Most people really don't believe in this Jesus, so they create their own.
