'Deserve' in the Bible

What [are] you to me, Tyre and Sidon, and all of the regions of Philistia? Are you repaying to me what is deserved? If you [are] recompensing me, I will return swiftly [and] quickly what you deserve on your head!

Look! I [am] rousing them from the place where you have sold them, and I will return what you deserve on your head!
