Joshua 1:18

18 And whosoever shall disobey thee, and whosoever shall not hearken to thy words as thou shalt command him, let him die; but be thou strong and courageous.

Joshua 1:18 Meaning and Commentary

Joshua 1:18

Whosoever [he be] that doth rebel against thy commandment,
&c.] Refuses to go over Jordan with his brethren the children of Israel, when commanded by Joshua so to do:

and will not hearken to thy words in all that thou commandest him;
or, if he does go over, yet will not obey orders to take such a post, or go against such a city, or march into such a part of the country:

he shall be put to death;
this part of military discipline they agree to, and hereby declare their entire submission to him as their general; some understand this as spoken by all Israel, and of their promise of obedience to Joshua, as their governor, in all things:

only be strong, and of a good courage;
which also is not to be understood as a condition of their submission and obedience, but as a hearty wish and prayer for him, that he might have strength and courage necessary to the great work he was engaging in, and which to see would be no small encouragement to follow and obey him.

Joshua 1:18 In-Context

16 And they answered Joshua and said, We will do all things which thou commandest us, and we will go to every place whither thou shalt send us.
17 Whereinsoever we hearkened to Moses we will hearken to thee; only let the Lord our God be with thee, as he was with Moses.
18 And whosoever shall disobey thee, and whosoever shall not hearken to thy words as thou shalt command him, let him die; but be thou strong and courageous.
