1 Samuel 17:37

David said moreover, The LORD that delivered me out of the paw of the lion, and out of the paw of the bear, he will deliver me out of the hand of this Philistine. And Saul said unto David, Go, and the LORD be with thee.

The Lord that delivered me out of the paw of the lion, х miyad (H3027)] - from the hand. It would have been natural for a youth, and especially an Oriental youth, to make a parade of his gallantry. But David's piety sank all consideration of his own prowess, and ascribed the success of those achievements to the divine aid, which he felt assured would not be withheld from him in a cause which so intimately concerned the safety and honour of His people.

Saul said ... Go, and the Lord be with thee. The pious language of the modest but valiant youth impressed the monarch's heart. He felt that it indicated the true military confidence for Israel, and therefore made up his mind, without any demur, to sanction a combat on which the fate of his kingdom depended, and with a champion supporting his interests apparently so unequal to the task. The tradition of the combat between David and Goliath, in which the latter was killed, is preserved among the Arabs; because he is mentioned in the Koran, where he is called Galut or Jalut. The Arabs also call the dynasty of the Philistine kings, who reigned in Palestine when the Hebrews came there, Galuliah or Jaluliah.
