You interpret that as His support for the temple? I don't, sound more like get rid of the scum to me. He predicted it's destruction, and would play no more a part in the coming kingdom.
NKJV:
Jesus Cleanses the Temple
13Now the Passover of the Jews was at hand, and Jesus went up to Jerusalem.
14And He found in the temple those who sold oxen and sheep and doves, and the money changers
John 2 NKJVdoing business. 15When He had made a whip of cords, He drove them all out of the temple, with the sheep and the oxen, and poured out the changers’ money and overturned the tables. 16And He said to those who sold doves, “Take these things away! Do not make My Father’s house a house of merchandise!” 17Then His disciples remembered that it was written, “Zeal for Your house [c]has eaten Me up.”
18So the Jews answered and said to Him, “What sign do You show to us, since You do these things?”
19Jesus answered and said to them, “Destroy this temple, and in three days I will raise it up.”
20Then the Jews said, “It has taken forty-six years to build this temple, and will You raise it up in three days?”
21But He was speaking of the temple of His body. 22Therefore, when He had risen from the dead, His disciples remembered that He had said this [d]to them; and they believed the Scripture and the word which Jesus had said.
"He predicted it's destruction"
True.
But,..."If" You truly had
Knowledge of The Scriptures,..... Then You'd Know that it was those who were Falsely Serving in that Temple, via the "Oral Law", & not "The House" itself. :
Mat 23:1 Then Jesus spoke to the multitudes and to his disciples,
Mat 23:2 saying, “The scribes and the Pharisees sat on Moses’ seat.
Mat 23:3 All things therefore whatever they tell you to observe, observe and do,
but don’t do their works; for they say, and don’t do.
Mat 23:4
For they bind heavy burdens that are grievous to be borne, and lay them on men’s shoulders; but they themselves will not lift a finger to help them.
Mat 23:5 But all their works
they do to be seen by men. They make their phylacteries broad, enlarge the fringes of their garments,
Mat 23:6 and love the place of honor at feasts, the best seats in the synagogues,
Mat 23:7 the salutations in the marketplaces, and to be called ‘Rabbi, Rabbi’ by men.
Mat 23:15
Woe to you, scribes and Pharisees, hypocrites! For you travel around by sea and land to make one proselyte; and when he becomes one, you make him twice as much a son of Gehenna as yourselves.
Mat 23:16
“Woe to you, you blind guides, who say, ‘Whoever swears by the temple, it is nothing; but whoever swears by the gold of the temple, he is obligated.’
Mat 23:17
You blind fools! For which is greater, the gold, or the temple that sanctifies the gold?
Mat 23:18 ‘Whoever swears by the altar, it is nothing; but whoever swears by the gift that is on it, he is obligated?’
Mat 23:19
You blind fools! For which is greater, the gift, or the altar that sanctifies the gift?
Mat 23:20 He therefore who swears by the altar, swears by it, and by everything on it.
Mat 23:21 He who swears by the temple, swears by it, and by him who has been living in it.
Mat 23:22 He who swears by heaven, swears by the throne of God, and by him who sits on it.
Mat 23:23
“Woe to you, scribes and Pharisees, hypocrites! For you tithe mint, dill, and cumin, and have
left undone the weightier matters of the law: justice, mercy, and faith. But you ought to have done these, and not to have left the other undone.
Mat 23:24
You blind guides, who strain out a gnat, and swallow a camel!
Mat 23:25
“Woe to you, scribes and Pharisees, hypocrites! For you clean the outside of the cup and of the platter, but within they are full of extortion and unrighteousness.
Mat 23:26
You blind Pharisee, first clean the inside of the cup and of the platter, that its outside may become clean also.
Mat 23:27
“Woe to you, scribes and Pharisees, hypocrites! For you are like whitened tombs, which outwardly appear beautiful, but inwardly are full of dead men’s bones, and of all uncleanness.
Mat 23:28
Even so you also outwardly appear righteous to men, but inwardly you are full of hypocrisy and iniquity.
Mat 23:29
“Woe to you, scribes and Pharisees, hypocrites! For you build the tombs of the prophets, and decorate the tombs of the righteous,
Mat 23:30 and say, ‘If we had lived in the days of our fathers, we wouldn’t have been partakers with them in the blood of the prophets.’
Mat 23:31
Therefore you testify to yourselves that you are children of those who killed the prophets.
Mat 23:32 Fill up, then, the measure of your fathers.
Mat 23:33
You serpents, you offspring of vipers, how will you escape the judgment of Gehenna?
Mat 23:34 Therefore behold, I send to you prophets, wise men, and scribes. Some of them you will kill and crucify; and some of them you will scourge in your synagogues, and persecute from city to city;
Mat 23:35
that on you may come all the righteous blood shed on the earth, from the blood of righteous Abel to the blood of Zachariah son of Barachiah, whom you killed between the sanctuary and the altar.
Mat 23:36 Most certainly I tell you,
all these things will come upon this generation.
