Lalu ia naik dan berbaring di atas anak itu. Ia meletakkan mulutnya di atas mulut anak itu, matanya di atas mata anak itu, dan telapak tangannya di atas telapak tangan anak itu. Ia merentangkan tubuhnya di atas anak itu, dan tubuh anak itu pun menjadi hangat.

And he spread himself upon him. [Targum] Yonoson rendered ‘וְאַלְהֵי עֲלוֹהִי’, an expression of weariness.26I.e., “he laid exhausted upon him.” There is a similar word in the Beraisa of Ha’azinu and in Sifrei. But Menachem rendered ‘וַיִּגְהַר’, an interpretation of the word according to its context, “he prostrated himself upon him.”27See I Melochim 18:42.
