What is the meaning of Mark 11:15-19?

15 And they come to Jerusalem: and Jesus went into the temple, and began to cast out them that sold and bought in the temple, and overthrew the tables of the moneychangers, and the seats of them that sold doves; 16 And would not suffer that any man should carry any vessel through the temple. 17 And he taught, saying unto them, Is it not written, My house shall be called of all nations the house of prayer? but ye have made it a den of thieves. 18 And the scribes and chief priests heard it, and sought how they might destroy him: for they feared him, because all the people was astonished at his doctrine. 19 And when even was come, he went out of the city. (Mark 11:15-19 KJV)

William Burkitt’s Commentary

No sooner had our blessed Saviour entered Jerusalem, but his first walk was to the temple, and his first work there was to purge and reform. All reformation of manners must begin at the house of God.

Yet observe, Our Lord’s business at the temple was not to ruin but reform it only. Places dedicated to public worship, if profaned and polluted, ought to be purged from their abuses, not pulled down and destroyed, because they have been abused. But what was the profanation of the temple, which so offended our Saviour; I answer, in the outward court of the temple there was a public mart or market kept, where were sold oxen, sheep, and doves, for sacrifice. For many of the Jews coming a hundred miles to the temple, it was burdensome to bring their sacrifices so far with them; wherefore the priests ordered that sheep and oxen, meal and oil, and such other requisites for sacrifice, should be had for money close by the altar, to the great ease of the offerer; nothing could be more plausible than this plea. But the fairest pretences cannot bear out a sin with God. Therefore our blessed Saviour, in a just indignation, whips out these chapmen, casts down their tables, and vindicates the honour and reputation of his Father’s house.

Learn hence, That there is reverence due to God’s house, for the owner’s sake, and for the service sake. Nothing but holiness can become the place where God is worshipped in the beauty of holiness.

Observe lastly, The reason which our Saviour gives for this act of his: Is it not written, says he, my house shall be called the house of prayer? Where by prayer is to be understood the whole worship and service of God, of which prayer is an eminent and principal part. That which gives denomination to a house is certainly the chief work to be done in that house. Now God’s house being called a house of prayer, certainly implies, that prayer is the chief and principal work to be performed in his house. Yet take we heed, that we set not the ordinances of God at variance, we must not idolize one ordinance and vilify another, but reverence them all.
