Dont tell anyone who healed me?

Matthew 12:16 Yet He warned them not to make Him known.

This is after Jesus healed all that came unto Him. Now, why does He command them not to spread the word on who did these life changing miracles? I thought Jesus wants them to testify of these things. Well, He does, however at this point, He had lots of ministry left to do. He needed to be low key, but the main reason, I believe, was because of His word. The bible declares that on a specific day in history, the Messiah would be declared king if the Jews and worshipped. That day was April 6th, 32 AD, the triumphal entry of Christ. He rode into Jerusalem on a donkey on the very day the word declared, as the crowds shouted out hosanna (save now) unto Him. He was to be worshipped as king then, as appointed in His word. How can a man orchestrate that, if He was just a man?
