But thou hast not called upon me. — The startling abruptness of the complaint has led many critics to question the genuineness of these verses (22-24). Their insertion, however, by a later writer would be at least as hard to understand as their having come from the hand of the same writer as the glowing picture that precedes them. May we not find the solution of the problem in the fact that Isaiah’s experience taught him that there would be in the future, as in the past, a dark as well as a bright side to the picture? that the mercies shown to the exiles would not be according to their merits, but to God’s great goodness? The worship of the restored exiles would be as that of the people had been in his own time, meagre and unthankful. Visions of failure alternate with the glowing hope that the ideal will be realised, and this alternation constitutes the great problem of the book, as it does of all like apocalyptic intimations.
But thou hast been weary. — Better, so that thou shouldest be weary. Others render it, Much less hast thou toiled for me. Sacrifices elsewhere than in the Temple were forbidden by the Law, and the prophet does not so much blame the people for not offering these as for not compensating for their absence by the true worship of which they were the symbols.
