"And the Lord will be a refuge for the oppressed, a refuge in times of distress." Rabbi Yochanan said, wherever it is written "oppressed" or "poor" in reference to Israel, the verse speaks of a situation where poverty will not cease from them until the destruction of the Temple.
"And those who know your name put their trust in you, for you, O Lord, have not forsaken those who seek you. Sing praises to the Lord, who dwells in Zion." Rabbi Yochanan said: From what happened in Zion we learn that God will not withhold retribution from those who destroy it. Rabbi Chanina said: "Sing praises to the Lord" - when will this happen? When God returns His Divine presence to Zion. Rabbi Yochanan said to him: "A verse supports your claim" (Psalm 102:17) "He shall regard the prayer of the destitute and shall not despise their prayer."
