In Numbers 13 God tells Moses ” Send thou men, that they may search the land of Canaan, which I give unto the children of Israel: of every tribe of their fathers shall ye send a man, every one a ruler among them.” Num 13:2
I see the key word here as “give”. The men are simply to report what they saw. To report back on the people that live there and what type of land it is, whether good or bad. God is giving them this promised gift of land so that they may become a nation. God brought them out of Egypt with a series of miracles so the Israelites should have lots of faith in God to deliver this gift to them.
When the men return they say that the land flows with “milk and honey” and bring back fruit. However they report that the people are strong. When you look further into it you see that there are nephelim in the land.
” 33 And there we saw the giants, the sons of Anak, which come of the giants: and we were in our own sight as grasshoppers, and so we were in their sight.” Num 13:33
The people want to work for this gift that God has given to them but they find that they’re not strong enough by their own works to obtain this gift themselves. It is a gift from God, no works are necessary.
There were two, Caleb and Joshua that try and convince the others that God will give the land that was promised:
“8 If the Lord delight in us, then he will bring us into this land, and give it us; a land which floweth with milk and honey.” Num 14:8
The people however believe the other spies which angers God, they are then to wander in the wilderness until the generation passes away and will not inherent this gift.
I see this story as a prophetic type of salvation. We don’t have the power on our own to work for salvation, the price is too high. It’s a gift, we simply have to believe. I see Joshua as a type of the Jew Caleb as a type of gentile which is grafted into the tribe of Judah. ” Save Caleb the son of Jephunneh the Kenezite” Num 32:12
Both Jews and Gentiles are able to inherit, but have to have faith in God’s promise.
