Charles H. Spurgeon on Psalms 116:3

See how the saints instead of lessening the dangers and tribulations, with which they are exercised by God, magnify them in figurative phraseology; neither do they conceal their distress of soul, but clearly and willingly set it forth. Far otherwise are the minds of those who regard their own glory and not the glory of God. The saints, that they may make more illustrious the glory of the help of God, declare things concerning themselves which make but little for their own glory. Wolfgang Musculus.

Verses 3-7. Those usually have most of heaven upon earth, that formerly have met with most of hell upon earth. The sorrows of death compassed me, and the pains of hell gat hold upon me: I found trouble and sorrow: (as Jonas crying in the belly of hell). But look upon him within two or three verses after, and you may see him in an ecstasy, as if he were in heaven; Ps 116:7: Return unto thy rest, O my soul; for the LORD hath dealt bountifully with thee. Matthew Lawrence.
