'Necessity' in the Bible

And those who know Your name [who have experienced Your precious mercy] will put their confident trust in You,For You, O Lord, have not abandoned those who seek You.

The Lord has looked down from heaven upon the children of menTo see if there are any who understand (act wisely),Who [truly] seek after God, [longing for His wisdom and guidance].

This is the generation (description) of those who diligently seek Him and require Him as their greatest need,Who seek Your face, even [as did] Jacob. Selah.

When You said, “Seek My face [in prayer, require My presence as your greatest need],” my heart said to You,“Your face, O Lord, I will seek [on the authority of Your word].”

I sought the Lord [on the authority of His word], and He answered me,And delivered me from all my fears.

Do not let those who wait [confidently] for You be ashamed through me, O Lord God of hosts;Do not let those who seek You [as necessary for life itself] be dishonored through me, O God of Israel,

Who satisfies your years with good things,So that your youth is renewed like the [soaring] eagle.

Glory in His holy name;Let the hearts of those who seek and require the Lord [as their most essential need] rejoice.
