John Trapp on Psalms 77:9

Verſ. 9. Hath God forgotten to be gracious?] So it ſeemeth ſometimes to thoſe that are long afflicted, and ſhort-ſpirited; But what ſaith the Prophet? Can a Woman forget her ſucking childe, that ſhe ſhould not have compaſſion on the Son of her womb?H[illegible: 1 letter]yt. Geor. yea they may forget (they may prove unnatural, and grow out of kind, as Medea, and thoſe Suevian women, who threw their young Children at the Romanes (under the conduct of Druſus, Son in Law to Auguſtus) inſtead of Darts) yet God will not forget his people, Iſa. 49.15. Indeed he can as ſoon forget himſelf, and change his nature.

Hath he in anger ſhut up his tender mercies?] Theſe things the Pſalmiſt ſpeaketh not as utterly deſpairing, but as one couragiouſly wraſtling againſt an old Manſlayer, and a miſgiving heart of his own. Homines vero ſecuri, & voluptatibus ebrii, nihil horum intelligunt. This is little underſtood by profane Senſualiſts, who therefore reap no great benefit by the reading of theſe Pſalms.
