Hadar

"Adod, brave(?). (1.) A son of Ishmael (Gen. 25:15); in 1 Chr." 1:30 written Hadad. "(2.) One of the Edomitish kings (Gen. 36:39) about the time of "Saul. Called also Hadad (1 Chr. 1:50, 51)." "It is probable that in these cases Hadar may be an error simply of transcription for Hadad.

"Adod is his help, the name given to Hadadezer (2 Sam. 8:3-12) in" 2 Sam. 10.
