In the book I am reading (Patrick Fairbairn, The Interpretation of Prophecy, 2nd ed., 1865), the abbreviation "sq." is used sometimes in referencing both Scripture and other books (as "Typology of Scripture, vol. i. p. 100 sq." or "Ezek xxvi. 7, sq."). What does "sq." mean in this context?
(Instances of this abbreviation's usage may be found at Google Books here.)
