Psalms 103:9

“He will not always chide, etc.] He sometimes does chide his children, though never but when they have done a fault; always for their sins, in order to bring them to a sense and acknowledgment of them, and to depart from them; not for chiding sake, as some parents, to gratify their passion and ill humour, who correct for their own pleasure; but the Lord chides and corrects for the profit of his children, that they may be partakers of his holiness; he ever does it for their good, but he will not always chide, or continue it ever: or “he will not always contend” f1435, strive with them, litigate a point with them, hold out a controversy, not being able to stand before him; he knows their frame,…”

“He will not always chide - Rebuke; contend; strive; for so the Hebrew word means. He will not always contend with people, or manifest his displeasure. See the notes at Isaiah 57:16; notes at Psalms 78:38-39. This implies that he may chide or rebuke his people, but that this will not be forever. He will punish them; he will manifest his displeasure at their sins; he will show that he does not approve of their course, but he will show that he “loves them,” and does not seek their ruin. Neither will he keep his anger for ever - The words “his anger” are supplied by the translators, but not improperly. The meaning is the same as in the former member of the sentence. He will not cherish hatred…”

“103:9 If the Lord were to constantly accuse or remain angry forever, no one would be left (see Isa 54:7-8; 57:16).”

“neither: Psa 30:5; Isa 57:16; Jer 3:5; Mic 7:18, Mic 7:19 Psalms 103:10”
