לֹא־תַעֲשֶׂ֣ה כֵ֔ן לַיהוָ֖ה אֱלֹהֶ֑יךָ כִּי֩ כָּל־תּוֹעֲבַ֨ת יְהוָ֜ה אֲשֶׁ֣ר שָׂנֵ֗א עָשׂוּ֙ לֵאלֹ֣הֵיהֶ֔ם כִּ֣י גַ֤ם אֶת־בְּנֵיהֶם֙ וְאֶת־בְּנֹ֣תֵיהֶ֔ם יִשְׂרְפ֥וּ בָאֵ֖שׁ לֵֽאלֹהֵיהֶֽם׃
No harás así á SEÑOR tu Dios; porque todo lo que SEÑOR aborrece, hicieron ellos á sus dioses; pues aun á sus hijos é hijas quemaban en el fuego á sus dioses.
Rashi
כי גם את בניהם FOR ALSO THEIR SONS [AND THEIR DAUGHTERS HAVE THEY BURNT IN THE FIRE TO THEIR GOD] — The word גם, “also”, is intended to include amongst those they used to burn, their parents also. R. Akiba related, “I once saw a heathen who bound his father before his dog which thereupon devoured him” (Sifrei Devarim 81:6).
Chizkuni
אשר שנא, “which He hates;” He hates these rituals even if you employ them in order to serve Him;” it would enrage him.
Sforno
כי כל תועבת ה' אשר שנא עשו לאלוהיהם, for even the manner in which they worshipped their idols is largely completely abhorrent in the eyes of the Lord.
