Deuteronomy 1:45

45.And ye returned and wept before the Lord. He here appeals to the testimony of their own conscience; for they never would have been brought to weeping and prayers, except by the force of their own feelings. Since, then, they were abundantly convinced, that a just punishment was inflicted upon their obstinacy, necessity drove them to seek after God: consequently they had no cause to complain, though God manifested Himself to be implacable.

In the last verse there is an ambiguity in the meaning of these words, “many days, according to the number of the days.” Some, rendering the verb in the pluperfect tense, “in which we had remained there,” (80) suppose that they still abode there another forty days. But it is equally probable; that an indefinite time is referred to: as if he had said, that the people delayed there a long time, from whence it might be inferred, that they lay like persons stupified, from lack of knowing what to do.

It is Kadesh-barnea to which Moses refers, from whence the spies had been sent forth; and not the Kadesh where Miriam died, and where the people murmured for want of water.
