Kommentar zu Jechezkiel 16:20

that you bore for Me If one had five sons, four of them were devoted to worshipping idols, and one he would set aside to attend school; and when he comes to offer up one of his sons to Molech, he offers up to it this one whom he had set aside to study Torahin the Midrash of Rabbi Tanchuma. But I say that “that you bore for Me” refers to the firstborn. Likewise, it is stated in this Book (20:26): “And I defiled them with their gifts, when they caused every one who opened the womb to pass.”
