New American Standard Bible (©1995)
"When the prince provides a freewill offering, a burnt offering, or peace offerings as a freewill offering to the LORD, the gate facing east shall be opened for him. And he shall provide his burnt offering and his peace offerings as he does on the sabbath day. Then he shall go out, and the gate shall be shut after he goes out.

King James Bible
Now when the prince shall prepare a voluntary burnt offering or peace offerings voluntarily unto the LORD, one shall then open him the gate that looketh toward the east, and he shall prepare his burnt offering and his peace offerings, as he did on the sabbath day: then he shall go forth; and after his going forth one shall shut the gate.

Darby Bible Translation
And when the prince shall offer a voluntary burnt-offering or voluntary peace-offerings unto Jehovah, the gate that looketh toward the east shall be opened for him and he shall offer his burnt-offering and his peace-offerings as he did on the sabbath-day, and he shall go out again, and the gate shall be shut after he hath gone out.

English Revised Version
And when the prince shall prepare a freewill offering, a burnt offering or peace offerings as a freewill offering unto the LORD, one shall open for him the gate that looketh toward the east, and he shall prepare his burnt offering and his peace offerings, as he doth on the sabbath day: then he shall go forth; and after his going forth one shall shut the gate.
