Boyd’s Bible Dictionary:

(ready for war). (1) Captain of King Jabin’s forces when defeated by Barak. Slain by Jael (Judg. 4; 5). (2) His children returned (Ezra 2:53; Neh. 7:55).

Concise Bible Dictionary:

1. Captain of the army of Jabin king of the northern Canaanites. His army was overthrown with great destruction, through God’s intervention, by Deborah and Barak. Sisera, thirsty and weary, sought shelter in the tent of Jael, who killed him with a tent peg driven through his head with a hammer—showing how God can energize a feeble instrument to work out His deliverance. See JAEL (Judg. 4:2-22; Judg. 5:20-31; 1 Sam. 12:9; Psa. 83:9).
2. Ancestor of some Nethinim who returned from exile (Ezra 2:53; Neh. 7:55).
