In Zechariah 5, the prophet saw a flying scroll. This is the type of book people had at that time. A scroll was material that had writing on one side and was blank on the other side. It was long and rolled up.
The scroll Zechariah saw was twenty cubits by ten cubits in size. There must be some significance for God to have given those dimensions. The Holy Place in the Tabernacle was these exact dimensions. The Holy Place was a symbol of the church in worship. That is where the table of showbread was. The priests ate it every seven days. That is where the candlestick and the altar of incense were located. When we worship today, those spiritual counterparts are there.
The scroll Zechariah saw had writing on both sides. This indicates that all that could be said or written had been done. Whatever could be said was settled. The scroll was flying over the whole earth. There are Christians all over the world. There are curses coming from the scroll. This is because those who do not accept and follow the commandments of God are condemned. These curses in Zechariah are said to be for those who steal and those who swear. It is possible that this is representative of adding to and taking away from God’s Word. Those two things basically cover all sins. Whatever one does in sinning is either taking away from God’s Word or adding to His Word. This is especially true for those who are professing to follow God.
The church has the responsibility to cover the world with God’s Word. Study the Bible. Learn all you can about the church, and if any of this is hard to understand, ask an adult to help you.
