And it was after these things that the Lord tried Abraham with the tenth trial, and said to him, Abraham! And he said, Behold me.

At Mount Moriah.

And Abraham said, The Word of the Lord will prepare for me a lamb; and if not, then thou art the offering, my son! And they went both of them together with a contrite heart.

And Abraham stretched out his hand, and took the knife to slay Izhak his son. Izhak answered and said to Abraham his father, My father, bind my hands rightly, lest in the hour of my affliction I tremble and confuse thee, and thy offering be found profane, and I be cast into the pit of destruction in the world to come. (Now) the eyes of Abraham reached unto the eyes of Izhak; but the eyes of Izhak reaching to the angels on high. And Izhak beheld them, but Abraham saw them not. In that hour came forth the angels on high, and said, these to these, Come, behold two righteous ones alone in the midst of the world: the one slayeth, the other is slain. He who slayeth deferreth not, and he who is to be slain stretcheth out his neck.

And He said, Abraham! Abraham! And Abraham answered in the language of the sanctuary, and said, Behold me.

And Abrahm prayed in the name of the Word of the Lord, and said, Thou art the Lord who seest, and art not seen. I pray for mercy before Thee, O Lord. It is wholly manifest and known before Thee that in my heart there was no dividing, in the time that Thou didst command me to offer Izhak my son, and to make him dust and ashes before Thee; but that forthwith I arose in the morning and performed Thy word with joy, and I have fulfilled Thy word. And now I pray for mercies before Thee, O Lord God, that when the children of Izhak offer in the hour of need, the binding of Izhak their father Thou mayest remember on their behalf, and remit and forgive their sins, and deliver them out of all need. That the generations who are to arise after him may say, In the mountain of the house of the sanctuary of the Lord did Abraham offer Izhak his son, and in this mountain of the house of the sanctuary was revealed unto him the glory of the Shekinah of the Lord.

And his concubine...and her name...
