2816. Abraham put forth his hand. That this signifies temptation even to the utmost of power, is evident from the series of things; for the Lord's most grievous and inmost temptations are treated of. The verses which precede treat of the preparation of the Human Divine for admitting and enduring them: here the act is treated of, which is expressed in the sense of the letter by "Abraham put forth his hand." That power is signified by the "hand" may be seen above (n. 878); here the utmost of power, because nothing but the act was wanting. It is according to the internal sense, that the Lord's Divine led His Human into the most grievous temptations (for by "Abraham" is meant the Lord as to His Divine), and this even to the utmost of power. The truth is that the Lord admitted temptations into Himself in order that He might expel thence all that was merely human, and this until nothing but the Divine remained.
 That the Lord admitted temptations into Himself, even the last, which was that of the cross, may be seen from the words of the Lord Himself, in Matthew:
Jesus began to show the disciples that He must suffer many things, and be killed. Then Peter took Him, and began to rebuke Him, saying, Spare Thyself, Lord; let this not be done unto Thee. But He turned and said unto Peter, Get thee behind Me, Satan; thou art an offense unto Me; for thou savorest not the things that are of God, but those that are of men (Matt. 16:21-23).
And more manifestly in John:
No one taketh My life from Me, but I lay it down of Myself. I have power to lay it down, and I have power to take it again (John 10:18).
And in Luke:
Behooved it not the Christ to suffer these things, and to enter into His glory? (Luke 24:26).
