(14) Heal me.--The prophet, consciously or unconsciously, contrasts himself with the deserters from Jehovah. He needs "healing" and "salvation," but he knows where to seek for them, and is sure that his Lord will not leave the work incomplete. The prayer of the prophet is like that of the Psalmist (Psalm 6:2; Psalm 30:2). In "thou art my praise" we have an echo of Deuteronomy 10:21; Psalm 71:6.

Verses 14-18. - A prayer of the prophet in this his hour of need. He who makes his boast of Jehovah may reckon upon his help. This is Jeremiah's principle. He prays for healing, Heal me... and I shall be - rather, that I may be - healed. He is one of those "broken in heart," whom Jehovah alone can "heal" (Psalm 147:3).

17:12-18 The prophet acknowledges the favour of God in setting up religion. There is fulness of comfort in God, overflowing, ever-flowing fulness, like a fountain. It is always fresh and clear, like spring-water, while the pleasures of sin are puddle-waters. He prays to God for healing, saving mercy. He appeals to God concerning his faithful discharge of the office to which he was called. He humbly begs that God would own and protect him in the work to which he had plainly called him. Whatever wounds or diseases we find to be in our hearts and consciences, let us apply to the Lord to heal us, to save us, that our souls may praise his name. His hands can bind up the troubled conscience, and heal the broken heart; he can cure the worst diseases of our nature.Heal me, O Lord, and I shall be healed,.... These are the words of the prophet, sensible of his own sins and backslidings, and of the part which he himself had in these corrupt and declining times; and being conscious of his own impotency to cure himself; and being fully satisfied of the power of the Lord to heal him; and being well assured, if he was healed by him, he should be thoroughly and effectually healed; therefore he applies unto him. Sins are diseases; healing them is the forgiveness of them; God only can grant this: or this may have respect to the consolation of him, whose soul was distressed, grieved, and wounded, with the consideration of the sins of his people, and the calamities coming upon them on that account:

save me, and I shall be saved; with a temporal, spiritual, and eternal salvation; save me from the corruptions of the times, from the designs of my enemies; preserve me to thy kingdom and glory; there are none saved but whom the Lord saves, and those that are saved by him are saved to a purpose; they can never perish:

for thou art my praise; the cause of it, by reason of mercies bestowed; the object of it, whom he did and would praise evermore, because of his favours, particularly the blessings of healing and salvation by him; see Psalm 103:1.
