My defence is of God Hebrew, מגני על אלהים, maginni gnal Elohim, my shield is upon God. He, as it were, carries my shield before me: see 1 Samuel 17:7. He does and will protect me against all mine enemies. Which saveth the upright in heart And therefore will save me whom he knows to be sincere and upright in my conduct toward him and toward Saul. God judgeth the righteous That is, defendeth, or avengeth, or delivereth, as this word is often used. To judge is properly to give sentence; which, because it may be done either by absolving and acquitting from punishment, or by condemning and giving up to punishment, therefore, it is sometimes used for the one and sometimes for the other, as the circumstances of the place determine. God is angry with the wicked every day Even then when his providence seems to favour them, and they are most secure and confident.
