“There was nothing in the ark save the two tables which Moses put therein at Horeb, when the LORD made a covenant with the children of Israel, when they came out of Egypt.”
King James Version (KJV)
5:9 To this day - When this history was first written; not when it was reviewed by Ezra: for after the return from Babylon, neither staves nor ark were any more seen.
5:11 By course - According to David's appointment, #1Chron 24:1 |- 31, 25:1 - 22, which was only for the ordinary service, but in extraordinary solemnities, such as this, they all came together.
