The New American Standard Bible is widely regarded as the most literally translated of 20th-century English Bible translations. According to the NASB's preface, the translators had a "Fourfold Aim" in this work:
These publications shall be true to the original Hebrew, Aramaic, and Greek.
They shall be grammatically correct.
They shall be understandable.
They shall give the Lord Jesus Christ His proper place, the place which the Word gives Him; therefore, no work will ever be personalized.
The NASB is a revision of the American Standard Version of 1901. This translation was an alternative to the (1946?1952/1971), itself a revision of the ASV, but considered by many to be theologically liberal.
