'Whoever' in the Bible

Then David said on that day, “Whoever strikes the Jebusites, let him go up through the [underground] water shaft to strike the lame and the blind, who are detested by David’s soul [because of their arrogance].” So [for that reason] they say, “The blind or the lame (Jebusites) shall not come into the [royal] house [of Israel].”

Behold, he has hidden himself [even] now in one of the ravines or in another place; and when some of your troops fall at the first attack, whoever hears about it will say, ‘There has been a defeat among the people who follow Absalom.’

The man told Joab, “Even if I were to feel the weight of a thousand pieces of silver in my hands, I would not put out my hand against the king’s son; for we all heard the king command you, Abishai, and Ittai, saying, ‘Protect the young man Absalom, for my sake.’

Now one of Joab’s young men stood by him and said, “Whoever favors Joab and is for David, let him follow Joab!”
