'Careful' in the Bible

But the man of God sent word to the king of Israel: “Be careful passing by this place, for the Arameans are going down there.”

Yet Jehu was not careful to follow the instruction of the Lord God of Israel with all his heart. He did not turn from the sins that Jeroboam had caused Israel to commit.

You are to be careful always to observe the statutes, the ordinances, the law, and the commandments He wrote for you; do not fear other gods.

I will never again cause the feet of the Israelites to wander from the land I gave to their ancestors if only they will be careful to do all I have commanded them—the whole law that My servant Moses commanded them.”
