S – 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 serve them or bow in worship to them. ⁸ Instead, be loyal to the Lord your God, as you have been to this day

Joshua 23:6–8 CSB

O – Commentary: 

Turning to impress the Israelites with their responsibility, Joshua passed on the very words Yahweh had armed him with when He instructed him to cross the Jordan: Be … strong; be careful to obey (cf. 1:6–9). Courage and obedience were the graces that led to the successful Conquest of Canaan and they were no less essential now

“Joshua,” in The Bible Knowledge Commentary: An Exposition of the Scriptures,

A – In Israel’s biggest conquest (crossing Jordan and defeating the nations there), God tells Joshua “Be strong; careful to obey.” Now that the “fight” is over, a new one is starting.  It is living in peace or “normalcy.”  We need to be as strong and vigilant daily as in a battle.

 R – Lord, we love you today and honor you above everyone else.  As we go through today, help us to be strong and obey Your Word.  Let us be just as vigilant to do what you command.  Help us be strong and courageous.
