Kommentar zu Tehillim 6:8

is dimmed Heb. עשׁשׁה, an expression of a lantern (עשׁשׁית), an eye which has impaired vision and seems to see through glass [held] before its eyes. Menachem (p. 139) defines it as an expression of decay, and so every expression of עשׁ, like (below 31:1 1) “and my bones are wasted away (עשׁשׁו).”

Decayed: – (The word) עָשְֽׁשָׁה ("is moth-eaten") is of the same origin (as עָשׁ, "moth"; cf) "the moth (עָשׁ) shall devour them" (Is. 1. 9), as if he had said "decays."

it has aged Heb. עתקה. My eye has aged and become old in that its light has dimmed. Menachem (p. 139) associated it with (Gen. 12:8): “And he moved (ויעתק) from there to the mountain.”
