Judges 14:19

And slew thirty men of them— This action is prefaced by a declaration, that the Spirit of the Lord came upon him, moving him to so extraordinary a deed, which no one has a right to imitate; for, 1st. The Philistines were considered as in a state of war with the Israelites; they were their tyrants and oppressors. 2nd. Samson was actually general of the Israelites, appointed by heaven to punish the Philistines. 3rdly. He was in this case no other than an instrument in the hand of God to punish offenders.
