'Priests' in the Bible

His priests fell by the sword, and his widows did not weep.

Moses and Aaron [were] among his priests; Samuel also [was] among [those who] called on his name. They called to Yahweh, and he answered them.

Let your priests clothe themselves with righteousness, and let your faithful sing for joy.

I will also clothe its priests with salvation, and its faithful will shout exuberantly for joy.
