Judges 14:6

And the Spirit of the Lord came mightily upon him, urging him on with great force, and he rent him as he would have rent a kid, taking hold of the beast with his bare hands and slaughtering him with the greatest ease, and he had nothing in his hand, no weapon of any kind; but he told not his father or his mother what he had done, he was conscious for the first time that the strength which he possessed was an unusual power, and he felt diffident about discussing it even with his parents, all the more so because they would have been startled by the account of the danger in which he had been.
