'Solemn' in the Bible

Like the flock for sacrifices, like the flock at Jerusalem during her appointed feasts, so will the desolate cities be filled with flocks of people. Then they will know [with confident assurance] that I am the Lord.”’”

They shall eat the grain offering, the sin offering and the guilt offering; and every devoted thing (offering) in Israel [dedicated by a solemn vow to God] shall be theirs.

But when the people of the land come before the Lord at the appointed feasts, he who enters by way of the north gate to worship shall go out by way of the south gate. And he who enters by way of the south gate shall go out by way of the north gate. No one shall return by way of the gate through which he entered, but shall go out straight ahead [through the opposite gate].

“At the feasts and the appointed festivals the grain offering shall be an ephah with a bull and an ephah with a ram, and with the lambs as much as one is able to give, and a hin of oil with an ephah.
