In his commentary on the Torah, The Rabbi Bahya ben Asher (Spain 1255-1340) writes that on Rosh Hashana we (‘ring in the new year’) by blowing the Shofar because that’s when we re-crown the 1 and only G-d as King of the universe, a process which is necessary in a kingship for there is no king without nation.
אין מלך בלא עם
רבינו בחיי (תלמיד הרשב”א) בבראשית לח, ל. ובבמדבר
(Ein Melech Below Om)
No king without nation
..and there we have it:
The only difference is that this phrase when referring to G-d becomes a palindrome and can be read backwards as well and still ‘ring’ true.
