Deuteronomy 5:32-33 Moses speaks to Israel at Mt. Sinai –
32 “Be careful to do as the LORD your God has commanded you; you are not to turn aside to the right or the left. 33 Follow the whole instruction the LORD your God has commanded you, so that you may live, prosper, and have a long life in the land you will possess.”
Joshua 1:6-7 The Lord to Joshua, Moses’ successor –
6 “Be strong and courageous, for you will distribute the land I swore to their fathers to give them as an inheritance. 7 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.”
Joshua 23:6-8 Joshua’s final instructions as he is about to die –
6 “Be very strong and continue obeying all that is written in the book of the law of Moses, so that you do not turn from it to the right or left 7 and so that you do not associate with these nations remaining among you. Do not call on the names of their gods or make an oath to them; do not worship them or bow down to them. 8 Instead, remain faithful to the LORD your God, as you have done to this day.
Isaiah 30:19-21 The prophet Isaiah speaks –
19 For you people will live on Zion in Jerusalem and will never cry again. He will show favor to you at the sound of your cry; when He hears, He will answer you. 20 The Lord will give you meager bread and water during oppression, but your Teacher will not hide Himself any longer. Your eyes will see your Teacher, 21 and whenever you turn to the right or to the left, your ears will hear this command behind you: “This is the way. Walk in it.”
