I will walk before the LORD in the land of the living.
Ver. 9. I will walk before the Lord] Indesinenter ambulabo. I will not only take a turn or two with God, go three or four steps with him, &c., but walk constantly and in all duties before him, with him, after him. Hypocrites do not walk with God, but halt with him, they follow him as a dog doth his master, till he comes by a carrion; they will launch no farther out into the main than they may be sure to return at pleasure safe again to the shore.
In the land] i.e. Here in this world, called also "the light of the living," Psalms 56:13; Psalms 52:5 Job 28:13 .
