American Standard Version (ASV):
Thine eyes did see mine unformed substance; And in thy book they were all written, [Even] the days that were ordained [for me], When as yet there was none of them.
King James Version (KJV):
Thine eyes did see my substance, yet being unperfect; and in thy book all [my members] were written, [which] in continuance were fashioned, when [as yet there was] none of them.
