“And the officers shall speak further unto the people, and they shall say, What man is there that is fearful and fainthearted? let him go and return unto his house, lest his brethren's heart faint as well as his heart.”
King James Version (KJV)
20:6 A vineyard - This and the former dispensation were generally convenient, but more necessary in the beginning of their settlement in Canaan, for the encouragement of those who should build houses or plant vineyards, which was chargeable to them, and beneficial to the common - wealth. Eaten of it - Heb. made it common, namely, for the use of himself and family and friends, which it was not, 'till the fifth year.
20:9 Make captains - Or rather, as the Hebrew hath it, they shall set or place the captains of the armies in the head or front of the people under their charge, that they may conduct them, and by their example encourage their soldiers. It is not likely they had their captains to make when they were just going to battle.
