'Required' in the Bible

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

God has looked down from heaven upon the children of menTo see if there is anyone who understands,Who seeks after God [who requires Him, who longs for Him as essential to life].

And I will walk at liberty,For I seek and deeply long for Your precepts.

I am Yours, save me [as Your own];For I have [diligently] sought Your precepts and required them [as my greatest need].

For there they who took us captive demanded of us a song with words,And our tormentors [who made a mockery of us demanded] amusement, saying,“Sing us one of the songs of Zion.”
