Targum for Exodus 1:16

וַיֹּ֗אמֶר בְּיַלֶּדְכֶן֙ אֶת־הָֽעִבְרִיּ֔וֹת וּרְאִיתֶ֖ן עַל־הָאָבְנָ֑יִם אִם־בֵּ֥ן הוּא֙ וַהֲמִתֶּ֣ן אֹת֔וֹ וְאִם־בַּ֥ת הִ֖יא וָחָֽיָה׃

and he said: ‘When ye do the office of a midwife to the Hebrew women, ye shall look upon the birthstool: if it be a son, then ye shall kill him; but if it be a daughter, then she shall live.’
