'Deserve' in the Bible
This thing is not good that you have done. As the Lord lives, you deserve to die, because you have not guarded your master, the Lord's anointed. And now see where the king's spear is and the bottle of water that was at his head.
And to Abiathar the priest the king said, Get to Anathoth to your own estate; for you deserve death, but I will not put you to death now, because you bore the ark of the Lord God before my father David and were afflicted in all my father endured.
And that He would show you the secrets of wisdom! For He is manifold in understanding! Know therefore that God exacts of you less than your guilt and iniquity [deserve].
Repay them according to their work and according to the wickedness of their doings; repay them according to the work of their hands; render to them what they deserve.
According as their deeds deserve, so will He repay wrath to His adversaries, recompense to His enemies; on the foreign islands and coastlands He will make compensation.
And the son said to him, Father, I have sinned against heaven and in your sight; I am no longer worthy to be called your son [I no longer deserve to be recognized as a son of yours]!
If then I am a wrongdoer and a criminal and have committed anything for which I deserve to die, I do not beg off and seek to escape death; but if there is no ground for their accusations against me, no one can give me up and make a present of me [ give me up freely] to them. I appeal to Caesar.
Though they are fully aware of God's righteous decree that those who do such things deserve to die, they not only do them themselves but approve and applaud others who practice them.
For He will render to every man according to his works [justly, as his deeds deserve]:
Even when we were dead (slain) by [our own] shortcomings and trespasses, He made us alive together in fellowship and in union with Christ; [He gave us the very life of Christ Himself, the same new life with which He quickened Him, for] it is by grace (His favor and mercy which you did not deserve) that you are saved ( delivered from judgment and made partakers of Christ's salvation).
How much worse (sterner and heavier) punishment do you suppose he will be judged to deserve who has spurned and [thus] trampled underfoot the Son of God, and who has considered the covenant blood by which he was consecrated common and unhallowed, thus profaning it and insulting and outraging the [Holy] Spirit [Who imparts] grace (the unmerited favor and blessing of God)?
Because they have poured out the blood of Your people (the saints) and the prophets, and You have given them blood to drink. Such is their due [they deserve it]!
