Charles H. Spurgeon on Psalms 129:6

Like grass upon the housetops. The enemies of Zion may have an elevated position in the nation, they may seem to promise growth, but having no root in themselves, like the hearers on the stony ground, give no promise of fruit. Their profession dies away and leaves no benefit to the church, as it claims no blessing from others. —William Wilson (1783-1873), in "The Book of Psalms, with an Exposition."
