'Understood' in the Bible

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].

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].

Until I came into the sanctuary of God;Then I understood [for I considered] their end.

Our fathers in Egypt did not understand nor appreciate Your miracles;They did not remember the abundance of Your mercies nor imprint Your lovingkindnesses on their hearts,But they were rebellious at the sea, at the Red Sea.

He has not dealt this way with any [other] nation;They have not known [understood, appreciated, heeded, or cherished] His ordinances.Praise the Lord! (Hallelujah!)
