תִּתְקְפֵ֣הוּ לָ֭נֶצַח וַֽיַּהֲלֹ֑ךְ מְשַׁנֶּ֥ה פָ֝נָ֗יו וַֽתְּשַׁלְּחֵֽהוּ׃
Ты превозносишь его навсегда, и он пасет; Ты изменил его лицо и отослал его прочь.
Rashi
You overpower him You are stronger than he; You overcome him with Your power, and he goes away from the world.
Malbim
Hope is a cruel illusion, that entices a man when he is young, only to fail him when he becomes old. For when a person dies, there is nothing more. To hope for a life after death is futile.
