A large crowd was following him because they were observing the miraculous signs he was performing on the sick.

The next day the large crowd that had come to the feast heard that Jesus was coming to Jerusalem. ¹ 

Then Jesus, when he looked up ¹  and saw that a large crowd was coming to him, said to Philip, “Where can we buy bread so that these people may eat?”

Jesus said, “Have ¹  the people sit down.” (Now there was a lot of grass in that place.) ²  So the men ³  sat down, about five thousand in number.

There was ¹  a lot of grumbling ²  about him among the crowds. ³  Some were saying, “He is a good man,” but others, “He deceives the common people.” ⁴ 

Now a large crowd of Judeans ¹  learned ²  that Jesus ³  was there, and so they came not only because of him ⁴  but also to see Lazarus whom he had raised from the dead.
