'Begin' in the Bible

The people, the ones commanding Gilead, {said to each other}, "Who [is] the man that will begin to fight against the {Ammonites}? He will be as head over all the inhabitants of Gilead."

because you [will] conceive and bear a son. No razor {will touch} his head, because the boy will be a {Nazirite of God} {from birth}. And it is he who will begin to deliver Israel from [the] hand of [the] Philistines."
