Halo and Hallel

Struck me today, the hebrew word for "shine" -- הל -- as in

בְּהִלּוֹ נֵרוֹ עֲלֵי ראשִׁי לְאוֹרוֹ אֵלֶךְ חשֶׁךְ and עֲטִישׁתָיו תָּהֶל אוֹר (Iyov 29 & 41)

being the Greek/English word of Halo.

Also then a possible connection of הל in the הלל of Chanuka to it's theme of Light. Not to mention the Ancient Greek word for Greece --- Ἑλλάς, Hellas
