Jeremiah 45:3

Therefore, having this ministry, as we have obtained mercy we faint not,

Wherefore we faint not, but if our outward man is destroyed our inward man is renewed day by day.

Let us not be weary of well doing; for in due season we shall reap if we faint not.

But, brothers, be not weary of well doing.

For consider him that has endured such a contradiction from sinners, that you may not become faint and weary in your minds.

Thou didst say, Woe is me now! for the LORD hath added grief to my sorrow; I fainted in my sighing, and I find no rest.

Therefore, having this ministry, as we have obtained mercy we faint not,

Let us not be weary of well doing; for in due season we shall reap if we faint not.

But, brothers, be not weary of well doing.

For consider him that has endured such a contradiction from sinners, that you may not become faint and weary in your minds.
