The New American Standard Bible (NASB) is a modern English language translation of the Bible. It is fully accessible online.
It is based on the 1901 American Standard Version, but seeks to provide a smoother reading in contemporary English. Old English "thee's" and "thou's" are replaced and words and phrases have been updated to the extent that their familiar meanings have changed. Sentences beginning with "and" have been changed, sometimes substituting "then" or "but" depending on the context. Through consultation with original Hebrew and Greek texts, some passages have been corrected.
The original NASB claims to be the most accurate English Bible translation, conveying the meaning without changing it to suit modern views.
The rights to the NASB are owned by the Lockman Foundation, an interdenominational nonprofit group which also has the rights to the Amplified Bible. The NASB should not be confused with the New American Bible, which is a Catholic translation.
