||Abraham then looked up and saw a ram caught by its horns in a thicket. He went and got the ram, sacrificing it as an all-burned offering in his son's place.
Vayisa Avraham et-eynav vayar vehineh-ayil achar ne'echaz basvach bekarnav vayelech Avraham vayikach et-ha'ayil vaya'alehu le'olah tachat beno.
||Abraham named the place 'God will See' (Adonoy Yir'eh). Today, it is therefore said, 'On God's Mountain, He will be seen.'
Vayikra Avraham shem-hamakom hahu Adonay Yir'eh asher ye'amer hayom behar Adonay yera'eh.
||God's angel called to Abraham from heaven a second time,
Vayikra mal'ach Adonay el-Avraham shenit min-hashamayim.
(Targum; Rashi). Or, 'saw a ram after it had been caught,' or 'after which it was caught;' (Hirsch; HaKethav VeHaKabbalah).
As we have seen, the original name of the place was Salem (Genesis 14:18). With yireh added to it, it became Yeru-shalem or Jerusalem (Midrash Tehillim 76).
