David said to God, “Was I not the one who decided to number the army? I am the one who sinned and committed this awful deed! ¹  As for these sheep – what have they done? O Lord my God, attack me and my family, ²  but remove the plague from your people!” ³ 

Joab son of Zeruiah started to count the men but did not finish. God was angry with Israel ¹  because of this, so the number was not recorded in the scroll ²  called The Annals of King David.
