There are several interesting things about the Old Testament law of separation for Israel.
1. They were not allowed to sow different seeds together. Deuteronomy 22:9, "Thou shalt not sow thy vineyard with divers seeds: lest the fruit of thy seed which thou hast sown, and the fruit of thy vineyard, be defiled."
In the Bible, seed is a type of the Word of God. Psalm 126:6, "He that goeth forth and weepeth, bearing precious seed, shall doubtless come again with rejoicing, bringing his sheaves with him." Luke 8:11, "Now the parable is this: The seed is the Word of God." The spiritual teaching is that we should not mix the Bible with other seed. The Bible is not one of God's books, it is THE Word of God!
2. They were not allowed to plow with an ox and an ass in the same yoke. Deuteronomy 22:10, "Thou shalt not plow with an ox and an ass together."
An ox in the Bible is symbolic of the man of God. Deuteronomy 25:4, "Thou shalt not muzzle the ox when he treadeth out the corn." I Timothy 5:17, 18, "Let the elders that rule well be counted worthy of double honour, especially they who labour in the word and doctrine. For the Scripture saith, Thou shalt not muzzle the ox that treadeth out the corn. And, The labourer is worthy of his reward." In I Timothy 5:17, the word "elder" is a synonym for "pastor" or "man of God," which means that the man of God should not be muzzled. Hence, the ox is symbolic of God's man. I Corinthians 9:9, "For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen?"
Just as the ox is symbolic of God's man, the ass is symbolic of false prophets and apostates. God is saying to us that just as He does not want His Word diluted, and just as He does not want His plan of salvation diluted, He does not want the testimony of His servants diluted by their being in a yoke with unbelievers.
3. They were not allowed to wear a garment with different materials such as wool and linen in the same garment. Deuteronomy 22:11, "Thou shalt not wear a garment of divers sorts, as of woollen and linen together."
A garment in the Bible is a type of salvation. The Apostle John reminds us that the linen garments worn by the redeemed are symbolic of righteousness. Revelation 19:8, "And to her was granted that she should be arrayed in fine linen, clean and white: for the fine linen is the righteousness of saints." This means that it is an abomination when anyone adds anything to salvation apart from faith in the finished work of Calvary. It is not salvation by faith plus baptism, it is not salvation by faith plus communion, it is not salvation by faith plus confirmation, it is not salvation by faith plus the sacraments, it is not salvation by faith plus good works. This is mixing material in the garment of salvation.
