20:1-9 In the wars wherein Israel engaged according to the will of God, they might expect the Divine assistance. The Lord was to be their only confidence. In these respects they were types of the Christian's warfare. Those unwilling to fight, must be sent away. The unwillingness might arise from a man's outward condition. God would not be served by men forced against their will. Thy people shall be willing, Ps 110:3. In running the Christian race, and fighting the good fight of faith, we must lay aside all that would make us unwilling. If a man's unwillingness rose from weakness and fear, he had leave to return from the war. The reason here given is, lest his brethren's heart fail as well as his heart. We must take heed that we fear not with the fear of them that are afraid, Isa 8:12.And what man is he that hath planted a vineyard, and hath not yet eaten of it?.... Which he has a right to do, and it is hard for him to be deprived of it, 1 Corinthians 9:7 or "hath not made it common" (k); according to the law in Leviticus 19:23. Three years the fruit of trees, and so of vines, might not be eaten; in the fourth, they were devoted to the Lord, and might be redeemed from the priest, and so made common; and on the fifth year were eaten in course; so the Targums of Jerusalem, Jonathan, and Jarchi, interpret it: "let him also go and return unto his house, lest he die in the battle, and another man eat of it"; or make it common, according to the above law: Aben Ezra seems to have another sense of this passage, deriving the word from another, which signifies piping and dancing, and observes, that it was a custom to sing, pipe, and dance in vineyards; and the Septuagint version is, "hath not been made merry of it"; though that may signify not having drank of the wine of it, to be made merry with it.
