And they took counsel - They consulted among themselves about the proper way to dispose of this money.
And bought with them - In Acts 1:18, it is said of Judas that "he purchased a field with the reward of his iniquity." By the passage in the Acts is meant no more than that he "furnished the means" or "was the occasion" of purchasing the field. It is not of necessity implied that Judas actually made the contract and paid down the money to buy a field to bury strangers in - a thing which would be in itself very improbable, but that it was "by his means" that the field was purchased. It is very frequent in the Scriptures, as well as in other writings, to represent a man as doing that which he is only the cause or occasion of another's doing. See Acts 2:23; John 19:1; Matthew 27:59-60.
The potter's field - Probably this was some field well known by that name, which was used for the purpose of making earthen vessels. The price paid for a field so near Jerusalem may appear to be very small; but it is not improbable that it had been worked until the clay was exhausted, and was neither suitable for that business nor for tillage, and was therefore considered as of little value.
To bury strangers in - Jews, who came up from other parts of the world to attend the great feasts at Jerusalem. The high priests, who regarded the "Gentiles" as abominable, would not be inclined to provide a burial-place for them.

To bury strangers in - Τοις ξενοις, the strangers, probably meaning, as some learned men conjecture, the Jewish strangers who might have come to Jerusalem, either to worship, or on some other business, and died there during their stay. See here, the very money for which the blessed Jesus was sold becomes subservient to the purpose of mercy and kindness! The bodies of strangers have a place of rest in the field purchased by the price at which his life was valued, and the souls of strangers and foreigners have a place of rest and refuge in his blood which was shed as a ransom price for the salvation of the whole world.

And they took counsel, and bought with them the potter's field, to bury (d) strangers in.
(d) Strangers and guests, whom the Jews could not endure to be joined with even after they were dead.

And they took counsel,.... With one another, considered of the matter, and deliberated about it a while; and at last came to a resolution,
and bought with them the potter's field, to bury strangers in: a field of no great value, or it could not have been bought so near Jerusalem for so small a sum as thirty pieces of silver. Grotius's conjecture seems to be a good one, that it was a field the potter had dug up for his use, and had made the most of it; so that it was good for nothing, but for the purpose for which these men bought it, "to bury strangers in": either such as were not of their own nation, as the Roman soldiers, many of which were among them, and who they did not suffer to be buried among them; or proselytes, or such as came from distant parts, at their three festivals, many of whom may be supposed to die at such times: now by this act of humanity in providing for the interment of strangers, they designed, and hoped to have covered their wickedness in bargaining with Judas to betray innocent blood, for this sure of money; but it was so ordered by divine providence, that this became a public and lasting memorial of their sin and infamy: for it follows,

Bought the potter's field. A field that had been used for the purpose of making pottery until it was worthless for other purposes and could be bought cheap. Potters' fields are still found in the Kedron Valley south of the city.
To bury strangers in. A burial place for the poor. The Jews usually provided their own tombs. Peter, in Acts 1:18, says that Judas fell down headlong and his bowels gushed out. The common explanation is that he hung himself on a tree overlooking the valley of Hinnom, that the rope gave way, and that he fell headlong upon the rocks below, a distance of forty to sixty feet.

They bought with them the potter's field - Well known, it seems, by that name. This was a small price for a field so near Jerusalem. But the earth had probably been digged for potters' vessels, so that it was now neither fit for tillage nor pasture, and consequently of small value. Foreigners - Heathens especially, of whom there were then great numbers in Jerusalem.
