We see no signs!

Remarking on Ps 74:9, one commentator has noted that:

The lament now says, "We do not see signs for us" Kraus suggests that this is a reference to omens or oracles in view of the parallelism. The absence of the signs is clearly related to the dilemma of no longer having a prophet. They were looking for some sign of fulfillment for the prophetic word that had promised them a future and given them hope for deliverance. But there was none; and there was no longer a prophet among them (especially true at the time Jeremiah and Ezekiel had been taken from them) They had no idea how long this silence will continue. A. Ross, A Commentary on The Psalms (Kregel, 2013), 2:590.

What's bitterly ironic about this complaint is that when the (preexilic) Jews had prophets, they scorned their warnings. Now that the predicted calamity has overtaken them, they no longer have prophets to consult in their distress. Having hated God's prophets when they had them, they now lament the absence of God's prophetic word.
