Charles Ellicott Commentary 1 Chronicles 19:4

"So Hanun took David`s servants, and shaved them, and cut off their garments in the middle, even to their buttocks, and sent them away." — 1 Chronicles 19:4 (ASV)

Shaved them — i.e., half of their beards (Samuel).

Very near their buttocks. — Literally, to the extremities. The chronicler has substituted a more dignified term for the one which appears in Samuel.

Cut off their garments. — To look like captives (Isaiah 20:4).
