Radak

c. 1160–1235 Jewish

LET US GO: This is what Israel is saying to each other in the days of the Messiah, to sing to the Lord that redeemed them. And we have already explained that “lechu” are words of ziruz (alacrity/enthusiasm) in the action, not literally walking.

Hebrew and Aramaic words are the commentator’s citations of the sacred text; the English translation that follows each is the translator’s.
