'Sternly' in the Bible

Then He sternly warned him and sent him away at once,

But he sternly ordered them again and again not to tell people who he was.

Jesus commanded them not to tell anyone; but the more He ordered them, the more widely they continued to proclaim it.

Peter answered him, "You are the Messiah!" Jesus sternly ordered them not to tell anyone about him.

Many people sternly told him to be quiet, but he started shouting even louder, "Son of David, have mercy on me!"
