מֵ֤י מָצוֹר֙ שַֽׁאֲבִי־לָ֔ךְ חַזְּקִ֖י מִבְצָרָ֑יִךְ בֹּ֧אִי בַטִּ֛יט וְרִמְסִ֥י בַחֹ֖מֶר הַחֲזִ֥יקִי מַלְבֵּֽן׃
Draw thee water for the siege, Strengthen thy fortresses; Go into the clay, and tread the mortar, Lay hold of the brickmould.
Targum Jonathan on Nahum
Collect water into the midst of thee; make strong thy fortresses; multiply power; cause service to be done in the clay; strengthen thy buildings.
