'Begin' in the Bible

The people, the princes of Gilead, said one to another, "What man is he who will begin to fight against the children of Ammon? He shall be head over all the inhabitants of Gilead."

for, behold, you shall conceive, and bear a son; and no razor shall come on his head; for the child shall be a Nazirite to God from the womb: and he shall begin to save Israel out of the hand of the Philistines."
