1 Chronicles 11:20

Abisai. His name is written without the middle i, in all this book. --- Three. Alexandrian Septuagint alone reads, "six." --- He was. Hebrew adds, "not;" evidently mistaking lo, "not," for lo, "ei." See 4 Kings viii. 10. "He lifted up his spear against 300 soldiers, and had a name among Three." (Kennicott)
