18 Blessed be the LORD God, the God of Israel,
Who alone works wonders.
19 And blessed be His glorious name forever;
And may the whole earth be filled with His glory.
Amen, and Amen.
Psalm 72:18-19
Blessed is actually a holy word. It's being revised in modern times to refer to things or events that please us. If we're happy about something or grateful for something, we say that we are "blessed."
But in the original Greek, the word "Blessed" implies something far more divine than anything of this earth. When Jesus gave us the Beatitudes he listed many "Blessings" that were available to us, and all of them instructed us to reach for something higher and better than our natural selves.
In this Psalm, written by King Solomon, the king offers up praise to God: and he gives God the only suitable thing he could offer. As he stood in the temple with the glory of God surrounding him like a cloud, Solomon offered back to God the Blessing that came in that glorious visitation. Solomon wished that the whole earth could experience the glory of God's Presence, as he did in that moment of holy anointing.
