Composing a text by hand demands an awareness of certain details that we can ignore when using a word processor. One of these details is if the next written word corresponds to the available space. At times, the space didn't for Hebrew scribes, and when this happened, they had several ways to navigate this situation. Let’s review some of these. For more information on these practices, see Tov’s discussion in chapters 4 and 5 of his book Scribal Practices. This list depends on and derives in part from his helpful discussions.
First, scribes could utilize the margin to finish the word. This practice is not uncommon. Here is a portion of column 2 of 1QIsaa illustrating this practice.
Fourth, it is possible that the scribe of 1QIsaa began a word and simply failed to finish it. See 1QIsaa Col 6:3.
Sixth, a scribe might resort to a smaller “font-size” to fit the word in the available space. See 1QIsaa Col 16:30 (the first line in the photo below).
