שכל את ידיו. כְּתַרְגּוּמוֹ, אַחְכִּימִינוּן – בְּהַשְׂכֵּל וְחָכְמָה הִשְׂכִּיל אֶת יָדָיו לְכָךְ וּמִדַּעַת, כִּי יוֹדֵעַ הָיָה כִּי מְנַשֶּׁה הַבְּכוֹר וְאַעַ"פִּ כֵן לֹא שָׁת יְמִינוֹ עָלָיו:

שכל את ידיו PLACING HIS HANDS DESIGNEDLY — Understand this as the Targum renders it: אחכמינון he put wisdom into them (viz., into his hands), meaning designedly and wisely he moved his hands for this purpose, intelligently and with full knowledge, for he knew that Manasseh was the first-born and yet he did not place his right hand upon him.
