Every valley shall be filled, and every mountain and hill shall be brought low; and the crooked shall be made straight, and the rough ways shall be made smooth;
Ver. 5. Every valley shall be filled] Every hole, or hollow, φαραγξ (Barathrum). Fainting of heart unfits the way for Christ, as well as the swelling hills of pride. Plain things will join in every point one with another; not so, rough and hollow things: so plain spirits close with God's truths; not so, those that are swollen, and uneven.
