Translations
The intent is that the Israelites bring to Yahweh whatever they would have sacrificed out in the open countryside—bringing it to the entrance of the Tent of Meeting, to the priest, to be offered as fellowship offerings to Yahweh.
This is so that the children of Yisra'el may bring to YHWH those sacrifices they would otherwise have slaughtered in the open field—bringing them to the entrance of the Ohel Mo'ed, to the kohen, and offering them as shelamim to YHWH.
To the end that the children of Israel may bring their sacrifices, which they offer in the open field, even that they may bring them unto the LORD, unto the door of the tabernacle of the congregation, unto the priest, and offer them for peace offerings unto the LORD.
For this reason the Israelites will bring to the LORD the sacrifices they have been offering in the open fields. They are to bring them to the priest at the entrance to the Tent of Meeting and offer them as sacrifices of peace offerings to the LORD.
