Isaiah 63:14

14.As a beast into a plain. Here, instead of “desert,” he makes use of the word “plain;” and the same meaning is drawn from what he says, that “the people walked through the depths without stumbling, as horses are wont to do in the desert.” In a word, he informs them that the Red Sea was no obstacle to the people marching through the midst of the depths, as if they were walking on level ground. (178)

A glorious name. This is in the same sense that he called it a little before “an everlasting name.” The people now argue with God, that if he once wished to obtain “a glorious name,” he must not now throw away all care about it; otherwise the remembrance of the benefits which he formerly bestowed on the fathers will be entirely blotted out.
