While he was in Jerusalem for the Passover festival, many believed in his name as they watched the signs he was doing.
In context
21But the temple he was speaking of was his own body. 22So when he was raised from the dead, his disciples remembered that he had said this, and they believed the Scripture and the word Jesus had spoken. 23While he was in Jerusalem for the Passover festival, many believed in his name as they watched the signs he was doing. 24But Jesus, for his part, did not entrust himself to them, because he knew them all, 25and he had no need for anyone to tell him about people: he himself knew what was inside each person.
