God is a righteous Judge – as (in the verse) Judge me, O Lord, according to my righteousness (Ps. 7:9); and its interpretation (is): God judges the righteous according to his righteousness and the wicked according to his wickedness, and this is what he means when he says:

Yea, a God that is provoked every day – as though to say, He judges the righteous, and He judges him who provokes God every day, when he repents not of his wickedness. And this is what he means below (by the words) if he turn not – if (אם) being used in the place of כי (when), as: "When (אם) the jubilee shall be" (Num. 36:4), where it stands in the place of כי or כאשר (when). And by every day he means "continually.⁠" And how was Saul provoking God? Because he was despising God's work and word, for he knew that David had been anointed as king by the command of God to succeed him, and (yet) he pursued him every day to kill him. You see he was planning every day to bring God's word to naught. And, moreover, David was innocent and had not sinned against him, and he wished to shed innocent blood. And, further, because he had sworn solemnly that he would not slay him. And for all these reasons it was right that He (God) should be spoken of as provoked.
