Charles Ellicott Commentary 1 Chronicles 19:2

"And David said, I will show kindness unto Hanun the son of Nahash, because his father showed kindness to me. So David sent messengers to comfort him concerning his father. And David`s servants came into the land of the children of Ammon to Hanun, to comfort him." — 1 Chronicles 19:2 (ASV)

Nahash Samuel omits, but adds “Hanun.” The omissions in each are perhaps accidental. Saul’s first campaign was against Nahash (1 Samuel 11:0).

Children of Ammon. —Sons of Ammon, like “sons of Israel.” The title calls attention to their tribal organization.

Because. —For. Samuel, “according as.”

Showed kindness to me. —The Hebrew phrase, which corresponds to the Greek of Luke 1:72. (See Revised Version.)

The rest of the verse is made clearer than in 2 Samuel 10:2 by slight changes and additions.
