Psalms 80:9

Thou preparedst room before it, and didst cause it to take deep root, and it filled the land.

Thou preparedst (room) before it - `Thou hast cleared out a place before it.' It answers to , "He gathered out the stones thereof" (i:e., of the vineyard), and refers to the dislodging of the original inhabitants to make way for Israel.

And didst cause it to take deep root - rather, as Hebrew 'it struck its roots' (Hengstenberg).
