Our eyes do yet fail [in looking] for our vain help: In our watching we have watched for a nation that could not save.
He afterwards adds, In our looking out, we looked out to a nation which could not save us. He. repeats the same thing in other words. Some consider a relative to be understood, “In our expectation with which we have expected,” etc.; but it seems not necessary. I, then, so connect the words of the Prophet, that the meaning is, that the Jews always turned their eyes to Egypt, as long as they stood as a state and kingdom and thus they willfully deceived themselves, because they took delight in their own vanity. The other clause which follows has the same meaning, In our expectation we expected a nation, etc.; and this clause is added as an explanation; for the Prophet explains how their eyes failed for a vain hope, or for a vain help, even because the people did not look to God, but only to the Egyptians.
