Jesus Cleanses the Temple
13 The Passover of the Jews was at hand, and Jesus went up to Jerusalem. 14 In the temple he found those who were selling oxen and sheep and pigeons, and the money-changers sitting there. 15 And making a whip of cords, he drove them all out of the temple, with the sheep and oxen. And he poured out the coins of the money-changers and overturned their tables. 16 And he told those who sold the pigeons, “Take these things away; do not make my Father’s house a house of trade.” 17 His disciples remembered that it was written, “Zeal for your house will consume me,” (Psalm 69:9).
18 So the Jews said to him, “What sign do you show us for doing these things?” 19 Jesus answered them, “Destroy this temple, and in three days I will raise it up.”
The temple, in Jesus’s eyes, was a place of worship and the merchants had disturbed the worship service of non-Jewish believers. Therefore, the temple was not being used for the purpose God intended.
Furthermore, this was the last Passover for Jesus, so he is referencing His future death and resurrection, when he says “in three days I will raise it up.” Jesus’s body is the temple.
