'Carefully' in the Bible

Above all, be strong and very courageous to carefully observe the whole instruction My servant Moses commanded you. Do not turn from it to the right or the left, so that you will have success wherever you go.

This book of instruction must not depart from your mouth; you are to recite it day and night so that you may carefully observe everything written in it. For then you will prosper and succeed in whatever you do.

They said to Joshua, "It was carefully reported to your subjects how the Lord your God commanded Moses his servant to assign you the whole land and to destroy all who live in the land from before you. Because of you we were terrified we would lose our lives, so we did this thing.

You have not deserted your brothers these many days to this day, but have [carefully] kept the obligation of the commandment of the Lord your God.

Only carefully obey the command and instruction that Moses the Lord’s servant gave you: to love the Lord your God, walk in all His ways, keep His commands, remain faithful to Him, and serve Him with all your heart and all your soul.”

Be very strong! Carefully obey all that is written in the law scroll of Moses so you won't swerve from it to the right or the left,

Watch yourselves carefully! Love the Lord your God!
