'Observing' in the Bible

if you obey the voice of the LORD your God by observing all his commands that I'm commanding you today. Do what is right in the sight of the LORD your God."

If only you listen well to the voice of Yahweh your God {by observing diligently} all of these commandments that I [am] commanding you {today}.

It shall be with him and he shall read it all the days of his life, that he may learn to fear the Lord his God, by carefully observing all the words of this law and these statutes,

"{And then} if you do not listen to the voice of Yahweh your God {by diligently observing} all of his commandments and his statutes that I [am] commanding you {today}, then all of these curses shall come upon you, and they shall overtake you:

"And all of these curses shall come over you, and they shall pursue you, and they shall overtake you {until you are destroyed}, because {you did not listen} to the voice of Yahweh your God, {by observing} his commandments and his statutes that he commanded you.

That's why I'm commanding you today to love the LORD your God by walking in his ways and by observing his commands, statutes, and ordinances, so that you may live long, increase, and so that the LORD your God may bless you in the land that you are about to enter to possess.
