(11) They were glad, and promised to give him money.--It may be noted (1) that the mention of the priests being "glad" is in common with St. Luke, and (2) that St. Mark does not name the specific sum which was promised as the price of blood.

Verse 11. - And they, when they heard it, were glad, and promised to give him money. And he sought (ἐζήτει) - he was seeking; he made it his business to arrange how the infamous plot might be managed - how he might conveniently deliver him unto them (πῶς εὐκαίρως αὐτὸν παραδῷ); literally, how at a convenient season he might betray him. And they,when they heard it, were glad; glad, because they saw the prospect of the accomplishment of their wishes; glad, because it was "one of the twelve" who covenanted to betray him. They promised to give him money. St. Matthew (Matthew 26:15) tells us the amount, namely, thirty pieces of silver, according to the prophecy of Zechariah (Zechariah 11:12), to which St. Matthew evidently refers. These pieces of silver were shekels of the sanctuary, worth about three shillings each. This would make the whole amount about £4 10s. of our money; less than half the value of the precious ointment with which Mary had anointed him. Some commentators, however, think that this was only an instalment of what they promised him if he completed his treasonable design. How he might conveniently deliver him unto them. St. Luke (Luke 22:6) explains this by saying, "in the absence of the multitude;" that is, when the people were not about him, and when he was in private with his disciples. And so he betrayed him at night, when he was alone with his disciples in the Garden of Gethsemane.

14:1-11 Did Christ pour out his soul unto death for us, and shall we think any thing too precious for him? Do we give him the precious ointment of our best affections? Let us love him with all the heart, though it is common for zeal and affection to be misunderstood and blamed; and remember that charity to the poor will not excuse any from particular acts of piety to the Lord Jesus. Christ commended this woman's pious attention to the notice of believers in all ages. Those who honour Christ he will honour. Covetousness was Judas' master lust, and that betrayed him to the sin of betraying his Master; the devil suited his temptation to that, and so conquered him. And see what wicked contrivances many have in their sinful pursuits; but what appears to forward their plans, will prove curses in the end.And when they heard it, they were glad,.... That such an opportunity offered, and from such a quarter, by one of his own disciples; so that it might be done more secretly and effectually, and with less blame to themselves:

and promised to give him money; any sum he should ask; and what was agreed upon were thirty pieces, or shekels of silver; and so the Ethiopic version here, instead of money, reads, "thirty pieces of silver"; See Gill on Matthew 26:15.

And he sought how he might conveniently betray him; after this promise, and upon this agreement: henceforward he sought the most fitting opportunity, and the best season of betraying his master into the hands of these men, when he was alone, and the multitude absent, and there was no danger of a tumult, or a rescue; See Gill on Matthew 26:16.
