A gap in line 15 ends verse 10 begins 11. Gap in line 16 ends verse 11 begins verse 12. And the gap 5 lines from the bottom ends verse 17 and begins 18. It is interesting that these spatial marks which indicate a break in thought correspond with later versification. There is no apparent reason for the 2 dots at the end of line 6.
Nothing is left out.
In some cases, as here, the proper word was then inserted between the lines above the wrong word. You will find an illustration of this in 5th and 6th lines from the bottom. The space at the end of line 2 marks the end of chapter two and line 3 starts with the first word of chapter three. 2mpl suffix is written above the line as added later. Similarly in the 5th line from the bottom the plural m in the last word ha-'akasiym is written above the line as crowded.
