'Necessity' in the Bible

“Listen to Me, you who pursue righteousness (right standing with God),Who seek and inquire of the Lord:Look to the rock from which you were cutAnd to the excavation of the quarry from which you were dug.

Seek the Lord while He may be found;Call on Him [for salvation] while He is near.

“And [the plain of] Sharon will be a place for flocks to graze,And the Valley of Achor a resting place for herds,For My people who seek Me [who long for Me and require My presence in their lives].
