שָׁ֣לַח מֶ֭לֶךְ וַיַּתִּירֵ֑הוּ מֹשֵׁ֥ל עַ֝מִּ֗ים וַֽיְפַתְּחֵֽהוּ׃
The king sent and loosed him; Even the ruler of the peoples, and set him free.
Rashi on Psalms
A king sent and released him Pharaoh, king of Egypt, sent his messengers and released him. A ruler of peoples, viz. Pharaoh, [sent] and loosed his bonds.
