עַל־כֵּן֙ גָּבְהָ֣א קֹמָת֔וֹ מִכֹּ֖ל עֲצֵ֣י הַשָּׂדֶ֑ה וַתִּרְבֶּ֨ינָה סַֽרְעַפֹּתָ֜יו וַתֶּאֱרַ֧כְנָה פארתו [פֹארֹתָ֛יו] מִמַּ֥יִם רַבִּ֖ים בְּשַׁלְּחֽוֹ׃
Therefore its stature was exalted Above all the trees of the field; And its boughs were multiplied, And its branches became long, Because of the multitude of waters, when it shot them forth.
Rashi on Ezekiel
because of abundant waters when it sent forth its branches through the abundant waters. When it sent forth its branches, i.e., when it grew its branches, and the expression “sending” applies to them, as “and sent forth branches.”
