'Blessed are' in the Bible

Then Saul said to David, "Blessed are you, my son David; {you will not only do many things, but also will always succeed}!" Then David went on his way and Saul returned to his place.

Kiss the Son lest he be angry and you perish [on the] way, for his anger burns quickly. Blessed are all [who] take refuge in him.

Blessed are [those who] observe justice, [he who] does righteousness at all times.

Blessed are you, O land, when your king is a son of nobility and your princes feast at the proper time-- to gain strength and not to get drunk.
