'Sternly' in the Bible

And their eyes were opened. Then Jesus warned them sternly, “Be sure that no one finds out!”

But he sternly warned them not to make him known.

Then He gave the disciples strict orders to tell no one that He was the Christ (the Messiah, the Anointed).

The crowd sternly told them to be quiet, but they cried out all the more, “Lord, Son of David, have mercy on us!”
