Has God forgotten to be gracious? has he in anger shut up his tender mercies? Selah.
All Commentaries on Psalms 77:9 Go To Psalms 77
Augustine of Hippo
AD 430
10. "Or will God forget to be merciful?" (ver. 9). In thee, from thee unto another there is no mercy unless God bestow it on thee: and shall God Himself forget mercy? The stream runneth: shall the spring itself be dried up? "Or shall God forget to be merciful: or shall He keep back in anger His mercies?" That is, shall He be so angry, as that He will not have mercy? He will more easily keep back anger than mercy.
