Deuteronomy 32:51

Deuteronomy 32:51 Meaning and Commentary

Deuteronomy 32:51

Because ye trespassed against me among the children of
Israel
By their unbelief, doubting whether God would give water or no to such a rebellious people, and by giving way to passion and wrathful expressions: and this was done

at the waters of Meribahkadesh;
so called, to distinguish it from another Meribah, where also there was a contention on account of water, ( Numbers 20:13 ) ( 27:14 ) :

in the wilderness of Zin;
where Kadesh was, and further describes and distinguishes this place; of the one we read in ( Exodus 17:7 ) ; and of the other, which is here referred to, in ( Numbers 20:1 Numbers 20:13 ) ;

because ye sanctified me not in, the midst of the children of Israel;
through their unbelief and disagreeable behaviour, they sanctified him not themselves, and gave no honour to him, nor were the cause of his being sanctified by the Israelites; and this was the reason why Moses and Aaron might not enter into the land of Canaan, ( Numbers 20:12 ) ( 27:12-14 ) .

50 You will die on that mountain as your brother Aaron died on Mount Hor,

51 because both of you were unfaithful to me in the presence of the people of Israel. When you were at the waters of Meribah, near the town of Kadesh in the wilderness of Zin, you dishonored me in the presence of the people.

52 You will look at the land from a distance, but you will not enter the land that I am giving the people of Israel."
