The word "behold" here shows that the priests were surprised by what they saw.
# They quickly drove him out of there
"They quickly forced him out of there" or "They quickly made him leave"
# Yahweh had struck him
This speaks of Yahweh making him sick as if Yahweh had hit him. Alternate translation: "Yahweh had made him ill" (See: [[rc://en/ta/man/translate/figs-metaphor]])
