Matthew
Matthew 21:38ESV·traditional attribution

But when the tenants saw the son, they said to themselves, ‘This is the heir. Come, let us kill him and have his inheritance.’

John Gill Reformed Baptist @doctorgill

But when the husbandmen saw the son,.... Whom many of them knew, though some did not: some were entirely ignorant of him; some knew him, but durst not confess him, yet were not injurious to him; others acted against light and conscience, with spite and malice, as did these men.

Albert Barnes Presbyterian @notesbybarnes

Verse 38. But when the husbandmen, etc. They determined to kill him; and as he was the only son, they supposed they could easily seize on the property. It was rented to them, was in their possession, and they resolved to keep it. This circumstance has probably no reference to any particular conduct of the Jews, but is thrown in to keep up the story, and fill up the narrative.

Jamieson-Fausset-Brown Reformed @jfbcommentary

But when the husbandmen saw the son, they said among themselves--Compare Gen 37:18-20; Joh 11:47-53. This is the heir--Sublime expression this of the great truth, that God's inheritance was destined for, and in due time is to come into the possession of, His own Son in our nature (Heb 1:2). come, let us kill him, and let us seize on his inheritance--that so, from mere servants, we may become lords.
