'Careful' in the Bible

But the children rebelled against Me; they did not walk in My statutes, nor were they careful to observe My ordinances, by which, if a man observes them, he will live; they profaned My sabbaths. So I resolved to pour out My wrath on them, to accomplish My anger against them in the wilderness.

I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances.
