Freewill Offerings Offered by the Prince (Ezekiel 46:12).
“And when the prince shall prepare a freewill offering, a whole burnt offering or peace offerings as a freewill offering to Yahweh, one shall open for him the gate that looks towards the east, and he shall prepare his whole burnt offering and his peace offerings, as he does on the sabbath day. Then he shall go out, and after he goes out one shall shut the gate.”
Provision is here made for freewill offerings over and above the prescribed offerings and sacrifices, to be offered by the prince at any time. These were expressions of gratitude and love. They may sometimes be offered on behalf of the people or sometimes be personal, no differentiation is made. But to offer such offerings specific access can be obtained through the inner east gate. The gate will be opened specifically for the purpose, so that he can sufficiently prepare it, and then closed immediately after he leaves. It is a kind of private access arrangement. The gate is not then left open for the public to see through, and worship before, after he has left, although they may presumably attend for the offering itself.
