In Hebrew, "jasher" (ישר) is derived from the root word "yashar" (ישר), which means "to be straight" or "to be upright". It can also connote righteousness, integrity, or honesty.

This book is not part of the traditional Hebrew Bible canon but is mentioned in the Old Testament in Joshua 10:13 and 2 Samuel 1:18.
The Assyrian etymology of "jasher" also contributes to its meanings.
