Perhaps the LORD will see my affliction and repay me with good for the cursing I receive today."

2 Chronicles 28:15
Then the men who were designated by name arose, took charge of the captives, and provided from the plunder clothing for the naked. They clothed them, gave them sandals and food and drink, anointed their wounds, and put all the feeble on donkeys. So they brought them to Jericho, the City of Palms, to their brothers. Then they returned to Samaria.

For you shall heap coals of fire on his head, and the LORD shall reward you.
