'Lengthen' in the Bible

If you walk in My ways, keeping My statutes and My commandments, as your father David did, then I will lengthen your days.”

“Enlarge the site of your tent [to make room for more children];Stretch out the curtains of your dwellings, do not spare them;Lengthen your tent ropesAnd make your pegs (stakes) firm [in the ground].

“[They shout], ‘Prepare for war against her;Arise, let us [take her by surprise and] attack her at noon.But alas, the daylight pales,The evening shadows grow long.
