Matthew 16:1

The Demand for a Sign The Pharisees also, with the Sadducees, came, and tempting, desired Him that He would show them a sign from heaven.

Here is a combination showing how far unionistic tendencies may lead if the object is opposition to Christ: the Pharisees, legalists, with their unceasing harping upon the details of Law and tradition: and the Sadducees, rationalists, with their denial of large parts of the Old Testament and all those doctrines that did not suit their reason. At other times these two Jewish sects were at sword's points, but for the purpose of resisting Christ they gladly unite their forces. In order to tempt Him, they come, in a malicious, deceitful manner. In a haughty way they request, demand, a sign from heaven, In chapter 12:38 they had not been so arrogant. Their bitterness toward Christ grew in the same measure as their inability to overcome Him. "Just as if the wonders which He had done hitherto were nothing at all, since they had been performed on earth only. As though they would say: Oh, these earthly miracles are nothing! If He would show that He was powerful in heaven, then one might believe Him. Not as though they had been willing even then to believe, but they in the meantime blaspheme these miracles in such a way, although they are far greater than those which they demanded from heaven. For to raise the dead, to give sight to the blind: that surpasses all signs which it is possible to show from heaven by as much as man, who is the likeness of God, surpasses heaven and all physical creatures, and eternal life the temporal creatures."
