Beginning of Psalm 105:
.הודוּ לה' קִרְאוּ בִשְׁמו. הודִיעוּ בָעַמִּים עֲלִילותָיו
Give thanks to the Lord, call out in His name; make His deeds known among the peoples.
Which people? Fellow Jews? Among non-Jews?
Is this an obligation, or just an expression of our gratitude to God?
Do we know of any instances where this was practiced?
