The heavens declare His righteousness, and all the people see His glory.@Psalm 97:6
Michael Praetorius (1571–1621)

Isaac Watts (1674–1748)

The Lord is come; the heav’ns proclaim
His birth; the nations learn His name;
An unknown star directs the road
Of eastern sages to their God.

All ye bright armies of the skies,
Go, worship where the Savior lies;
Angels and kings before Him bow,
Those gods on high and gods below.

Let idols totter to the ground,
And their own worshippers confound;
But Judah shout, but Zion sing,
And earth confess her sovereign king.
