John Gill, on Luke 1:8

“And it came to pass, when he executed the priestly function in the order of his course before God,”

“And it came to pass, that while he executed the priest's office,.... To which he was called and ordained, even to offer gifts and sacrifices for men; whilst he was in the way of his duty, when oftentimes God appears to, and in favour of his people; whilst he was performing it, before God; in the temple, where was the symbol of the divine presence, before the altar of the Lord; and as having the fear of God before his eyes; considering himself as in the sight of God, and doing his work faithfully and sincerely: in the order of his course; taking his turn in the order of the course of Abia, to which he belonged; See Gill on Luk 1:5.”
