'Regarding' in the Bible

This [is] the sign for you that will come regarding your two sons Hophni and Phinehas: they will both die on the same day!

Then Samuel said to all Israel, "Look, I have listened to your voice regarding all that you have said to me, so I have set a king over you.

Here I am! Testify against me before Yahweh and before his anointed one! Whose ox have I taken? Or whose donkey have I taken? Or whom have I exploited? Whom have I oppressed? Or from whose hand have I taken a bribe, that I may shut my eyes {regarding} him?-then I will restore it to you."

And who would listen to you regarding this matter? For as the share of the one who went down into the battle, so the share of the one who remained with the baggage will be. They will share alike."
