'Come Before the Lord' in the Bible

And on the eighth day he shall take for him two turtledoves, or two young pigeons, and come before the LORD unto the door of the tabernacle of meeting, and give them unto the priest:

But when the people of the land shall come before the LORD in the solemn feasts, he that enters in by the way of the north gate to worship shall go out by the way of the south gate; and he that enters by the way of the south gate shall go out by the way of the north gate: he shall not return by the way of the gate by which he came in, but shall go out opposite it.

With what shall I come before the LORD, and bow myself before the high God? shall I come before him with burnt offerings, with calves a year old?
