1:18 Now this man {q} purchased a field with the reward of iniquity; and {r} falling headlong, he burst asunder in the midst, and all his bowels gushed out.
(q) Luke did not consider Judas' purpose, but that which followed it, and so we used to say that a man has done himself harm, not that he wanted and intended to, but in respect of that which followed.
(r) The Greek words signify this much, that Judas fell down flat and was torn apart in the middle, with a tremendously great noise.
1:18 This man purchased a field. He returned the bribe money to the priests, who used it to purchase the potter's field. Peter here intends to say that his money bought the field. The Greek verb ktaomai, rendered purchased, has the form that means caused to be purchased.
Falling headlong. Mt 27:5 says he hanged himself. Peter tells some additional particulars, which Matthew omitted. He probably hanged himself on a tree projecting over the precipices of the Valley of Hinnom, and afterwards, on account of the rope or limb breaking, fell headlong with such force as to burst his body open on the jagged rocks. This is the traditional account of his death.
1:18 This man purchased a field with the reward of iniquity - That is, a field was purchased with the reward of his iniquity; though very possibly Judas might design the purchase. And falling down on his face - It seems the rope broke before, or as he died.
1:15-26 The great thing the apostles were to attest to the world, was, Christ's resurrection; for that was the great proof of his being the Messiah, and the foundation of our hope in him. The apostles were ordained, not to wordly dignity and dominion, but to preach Christ, and the power of his resurrection. An appeal was made to God; Thou, Lord, who knowest the hearts of all men, which we do not; and better than they know their own. It is fit that God should choose his own servants; and so far as he, by the disposals of his providence, or the gifts of his Spirit, shows whom he was chosen, or what he has chosen for us, we ought to fall in with his will. Let us own his hand in the determining everything which befalls us, especially in those by which any trust may be committed to us.
