And let us not grow weary while doing good, for in due season we
shall reap if we do not lose heart.
2 Thessalonians 3:13
But as for
you, brethren, do not grow weary in
1 Corinthians 15:58
Therefore, my beloved brethren, be steadfast, immovable, always
abounding in the work of the Lord, knowing that your labor is not in
vain in the Lord.
For consider Him who endured such hostility from sinners against
Himself, lest you become weary and discouraged in your souls.
