Charles H. Spurgeon on Psalms 80:9

"Thou preparedst room before it." The weeds, brambles, and huge stones were cleared; the Amorites, and their brethren in iniquity, were made to quit the scene, their forces were routed, their kings slain, their cities captures, and Canaan became like a plot of land, made ready for a vineyard. "And didst cause it to take deep root, and it filled the land." Israel became settled and established as a vine well rooted, and then it began to flourish and to spread to every side. This analogy might be applied to the experience of every believer in Jesus. The Lord has planted us, we are growing downward, "rooting roots, "and by his grace we are also advancing in manifest enlargement. The same is true of the church in a yet closer degree, for at this moment through the goodwill of the dresser of the vineyard her branches spread far and wide.
