Deuteronomy 32:51

51 For ye trespassed against me, in the midst of the sons of Israel, at the Waters of Against-saying, in Kadesh, of the desert of Zin; and ye hallowed not me among the sons of Israel. (For both of you trespassed against me, before the Israelites, at the waters of Meribah-Kadesh, in the wilderness of Zin; for ye did not uphold my holiness among the Israelites.)

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 ) .

Deuteronomy 32:51 In-Context

49 Go thou up into this hill Abarim, that is, passing, into the hill of Nebo, which is in the land of Moab, (over) against Jericho; and see thou the land of Canaan, which I shall give to the sons of Israel to hold, (Go thou up to the Abarim Mountains, that is, to The Passages, yea, onto Mount Nebo, which is in the land of Moab, opposite, or east of, Jericho; and see thou the land of Canaan, which I shall give to the Israelites for their possession,)

50 and die thou there in this hill. Into which hill thou shalt go up, and thou shalt be joined to thy peoples, as Aaron, thy brother, was dead in the hill of Hor, and was put to his peoples. (and then thou shalt die there on that mountain. Yea, thou shalt go up onto this mountain, and thou shalt join thy people, like when thy brother Aaron died on Mount Hor, and he joined his people.)

51 For ye trespassed against me, in the midst of the sons of Israel, at the Waters of Against-saying, in Kadesh, of the desert of Zin; and ye hallowed not me among the sons of Israel. (For both of you trespassed against me, before the Israelites, at the waters of Meribah-Kadesh, in the wilderness of Zin; for ye did not uphold my holiness among the Israelites.)

52 Opposite (thee), thou shalt see the land, and thou shalt not enter into it, which I shall give to the sons of Israel. (And thou shalt look across, and see the land, but thou shalt not enter into it, yea, the land which I shall give to the Israelites.)
