Then they cried unto the Lord in their trouble - The language in this verse is repeated in this psalm in Psalms 107:13, Psalms 107:19, Psalms 107:28 - as if this were the main subject of the psalm, that when the people of God in different circumstances, or under various forms of trouble, call upon God, he hears them and delivers them.
And he delivered them out of their distresses - The verb from which the noun used here is derived has the idea of being “narrow, straitened, compressed.” Hence, the word comes to be used in the sense of distress of any kind - as if one were pressed down, or compressed painfully in a narrow space.
