'Length' in the Bible

He asked life of thee, and thou gavest it him, even length of days for ever and ever.

Only -- goodness and kindness pursue me, All the days of my life, And my dwelling is in the house of Jehovah, For a length of days!

Who is the man who desires lifeAnd loves length of days that he may see good?

You, indeed, have made my days short in length,and my life span as nothing in Your sight.Yes, every mortal man is only a vapor.Selah

With length of days I satisfy him, And I cause him to look on My salvation!

Thy testimonies have been very stedfast, To Thy house comely is holiness, O Jehovah, for length of days!
