Thou hast made the earth to tremble - This refers, doubtless, to some calamity that might be compared with an earthquake - some disaster, discomfiture, or defeat that had shaken their hopes, as a city is shaken by an earthquake. Such comparisons are common in the Scriptures.
Thou hast broken it - As if it were broken up, or convulsed.
Heal the breaches thereof - That is, Appear for thy people, and repair their disasters, as if after an earthquake thou shouldst appear and fill up the rents which it had made. The prayer is that he would place things in their former condition of prosperity and success.
For it shaketh - It is convulsed or agitated. That is, there is still commotion. Things are unsettled and disturbed. The prayer is, that there might be stability or continued success.
