'Weary' in the Bible

Let us not be weary in doing good, for we will reap in due season, if we don't give up.

But you, brothers, don't be weary in doing well.

For consider him who has endured such contradiction of sinners against himself, that you don't grow weary, fainting in your souls.

You have perseverance and have endured for my name's sake, and have not grown weary.
