“And the covert for the sabbath that they had built in the house, and the king's entry without, turned he from the house of the LORD for the king of Assyria.”
King James Version (KJV)
16:18 The covert - The form and use whereof is now unknown. It is generally understood of some building, either that where the priests after their weekly course was ended, abode until the next course came; which was done upon the sabbath - day: or that in which the guard of the temple kept their station; or that under which the king used to sit to hear God's word, and see the sacrifices; which is called, the covert of the sabbath, because the chief times in which the king used it for those ends, was the weekly sabbath, and other solemn days of feasting, or fasting (which all come under the name of sabbaths in the Old Testament) upon which the king used more solemnly, to present himself before the Lord, than at other times. The entry - By which the king used to go from his palace to the temple.
