"The people heard with trembling. The convicting Spirit of God spoke to their hearts. Many were led to search the Scriptures with new and deeper interest, the intemperate and immoral were reformed, others abandoned their dishonest practices, and a work was done so marked that even ministers of the state church were forced to acknowledge that the hand of God was in the movement. GC 367.1"
"Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?"

When Jesus drew near to Jerusalem attended by the rejoicing multitudes that, with shouts of triumph and the waving of palm branches, heralded Him as the Son of David, the jealous Pharisees called upon Him to silence them; but Jesus answered that all this was in fulfillment of prophecy, and if these should hold their peace, the very stones would cry out.

And the blind and the lame came to him in the temple; and he healed them. And when the chief priests and scribes saw the wonderful things that he did, and the children crying in the temple, and saying, Hosanna to the Son of David; they were sore displeased, And said unto him, Hearest thou what these say? And Jesus saith unto them, Yea; have ye never read, Out of the mouth of babes and sucklings thou hast perfected praise?"
