'Carefully' in the Bible

please turn your attention to observe carefully and listen to the prayer of your servant today that I am presenting to you day and night on behalf of your servants, the Israelis.

But if you return to Me and carefully observe My commands, even though your exiles were banished to the ends of the earth, I will gather them from there and bring them to the place where I chose to have My name dwell.”

So after thinking it over carefully, I accused the officials and nobles openly, "Every one of you is charging your fellow countrymen interest!" So I opened a public investigation against them.

join with their noble brothers and commit themselves with a sworn oath to follow the law of God given through God’s servant Moses and to carefully obey all the commands, ordinances, and statutes of Yahweh our Lord.
