De 20:1
20:1 When {a} thou goest out to battle against thine enemies,
     and seest horses, and chariots, [and] a people more than
     thou, be not afraid of them: for the LORD thy God [is] with
     thee, which brought thee up out of the land of Egypt.

     (a) Meaning, upon just occasion: for God does not permit
         his people to fight every time it seems good to them.

De 20:4
20:4 For the LORD your God [is] he that {b} goeth with you, to
     fight for you against your enemies, to save you.

     (b) Is present to defend you with his grace and power.

De 20:5
20:5 And the officers shall speak unto the people, saying, What
     man [is there] that hath built a new house, and hath not
     {c} dedicated it? let him go and return to his house, lest
     he die in the battle, and another man dedicate it.

     (c) For when they first entered to dwell in a house, they
         gave thanks to God, acknowledging that they had that
         benefit by his grace.

De 20:6
20:6 And what man [is he] that hath planted a vineyard, and hath
     not [yet] {d} eaten of it? let him [also] go and return
     unto his house, lest he die in the battle, and another man
     eat of it.

     (d) The Hebrew word signifies to make common or profane,
         @Le 19:25

De 20:11
20:11 And it shall be, if it make thee answer of {e} peace, and
      open unto thee, then it shall be, [that] all the people
      [that is] found therein shall be tributaries unto thee,
      and they shall serve thee.

      (e) If it accept peace.

De 20:15
20:15 Thus shalt thou do unto all the cities [which are] very
      far off from thee, which [are] not of the cities of these
      {f} nations.

      (f) For God had appointed the Canaanites to be destroyed,
          and made the Israelites the executers of his will,
          @De 7:1.

De 20:19
20:19 When thou shalt besiege a city a long time, in making war
      against it to take it, thou shalt not destroy the trees
      thereof by forcing an axe against them: for thou mayest
      eat of them, and thou shalt not cut them down (for the {g}
      tree of the field [is] man's [life]) to employ [them] in
      the siege:

      (g) Some read: For man shall be instead of the tree of the
          field, to come out in the siege against you.
