John Trapp on Isaiah 38:12

Ver. 12. Mine age is departed] Or, my generation, or, my habitation: here I have no ſettled abode, no continuing City, but am flitting, as a ſhepherds ſhed.

I have cut off like a weaver my life] By my ſins I have ſhortned my daies, as Gen. 38.7.10. Or rather, God as a weaver that hath finiſhed his web, cutteth me out of the Loom of life. We know what the Poets fain of the Fates, Clotho colum bajulat, Lacheſis trabit, Atropos occat.

He will cut me off with pining ſickneſſe] Or, from the thrum; for the ſame Hebrew word ſignifieth both; becauſe of the thinneſ, and weakneſs of it.

From day even to night] So that by night I ſhall be dead, as they ſtory of the Ephemerobii; and as Ariſtotle writeth that the River Hypanis in Thracia every day bringeth forth little bladders, out of which come certain flies, which are thus bred in the morning, fledgd at noone, and dead at night.
