'Attend' in the Bible

Do you not know that those who perform sacred services eat the food of the temple, and those who attend regularly to the altar have their share from the altar?

and to make it your ambition to lead a quiet life and attend to your own business and work with your hands, just as we commanded you,

“For the eyes of the Lord are toward the righteous,And His ears attend to their prayer,But the face of the Lord is against those who do evil.”
