'Punish' in the Bible

Then all the people came and encouraged David to eat food while it was still day. But David took an oath saying, "God will punish me severely if I taste bread or anything whatsoever before the sun sets!"

Today I am weak, even though I am anointed as king. These men, the sons of Zeruiah, are too much for me to bear! May the Lord punish appropriately the one who has done this evil thing!"

Say to Amasa, 'Are you not my flesh and blood? God will punish me severely, if from this time on you are not the commander of my army in place of Joab!'"
