מְתִיבָא קָל רוּחָא דְקוּדְשָׁא וְאָמְרָא דְאִין מַנְשְׁיֵנָא לִיךְ יְרוּשְׁלֶם אַנְשְׁיָה לִימִינִי.
1. forget | תִּשְׁכַּח – As this verb is normally transitive, some fill in an assumed object: "let my right hand forget its capabilities, power, or movement (Sforno, Metzudat David), or: the melody (Radak). The commentary attributed to Rashbam, instead, suggests that the verb be understood as passive: "will be forgotten", while the Northern French commentary suggests that "תִּשְׁכַּח" is a second person address to Hashem, "may You forget my right hand". Cf. Hoil Moshe that perhaps the word should be read with the letters reversed, as if written "תכחש", to "grow lean" or "wither". Such metathesis happens elsewhere as well: "כבשה"="כשבה" and "שמלה"="שלמה".
