'Great Things' in the Bible

Jehovah will cut off all smooth lips, and the tongue speaking great things:

And thy justice, O God, even to height, who didst great things: O God, who like thee?

They forgat God saving them, doing great things in Egypt

Song of ascensions to David. O Jehovah, my heart was not lifted up, and mine eyes were not exalted, and I went not in great things and in wonders above me.
