“Thy servant slew both the lion and the bear: and this uncircumcised Philistine shall be as one of them, seeing he hath defied the armies of the living God.”
King James Version (KJV)
17:37 The Lord, &c. - The lion and the bear were only enemies to me and my sheep, and it was in defence of them I attacked them. But this Philistine is an enemy to my God and his people, and it is for their honour that I attack him.
17:38 Armour - With armour taken out of his armoury. He seems to speak of some military vestments which were then used in war, and were contrived for defence; such as buff - coats are now.
