וַיַּפֵּל֩ יְהוָ֨ה אֱלֹהִ֧ים ׀ תַּרְדֵּמָ֛ה עַל־הָאָדָ֖ם וַיִּישָׁ֑ן וַיִּקַּ֗ח אַחַת֙ מִצַּלְעֹתָ֔יו וַיִּסְגֹּ֥ר בָּשָׂ֖ר תַּחְתֶּֽנָּה׃
Targum Jonathan on Genesis
And the Lord God threw a deep slumber upon Adam, and he slept. And He took one of his ribs, it was the thirteenth rib of the right side, and closed it up with flesh.
