In Jeremiah 4:31, this signifies sorrow from falsities that extinguish spiritual life. (Apocalypse Explained 315[17])

3733. 'If God will be with me, and guard me on this road on which I am walking' means the ever-present Divine. This is clear from the meaning of 'God being with someone, and guarding him on the road on which he walks' as the ever-present Divine. For these words are used in reference to the Lord, the very Essence of whose life was Jehovah. His entire life from earliest childhood through to its final stage was the ever-present Divine, and this was so even to the attainment of the perfect union of the Human Essence with the Divine Essence.
