'Soldiers' in the Bible

David took from him 1,000 chariots, 7,000 horsemen, and 20,000 foot soldiers (infantrymen). David also hamstrung [nearly] all the chariot horses [to make them lame and useless], but left enough of them for 100 chariots.

The rest of the soldiers he placed in the hand of Abishai his brother, and they lined up against the Ammonites.

But the Arameans fled before Israel, and David killed of the Arameans 7,000 charioteers and 40,000 foot soldiers, and put to death Shophach the commander of the army.
