1 Chronicles 21:15,16

God sent an angel unto Jerusalem to destroy it, &c. This seems to import that there were more angels than one employed to effect this destruction in different parts of the country: and that the angels, sent to Jerusalem, had begun to slay some of its inhabitants. The Lord beheld, and repented him of the evil Probably because he beheld their serious repentance. David and the elders clothed in sackcloth That is, in mourning garments; fell on their faces Humbling themselves before God for their sins, and deprecating his wrath against the people.
