הַמָּאֹ֤ור הַקָּטֹן֙ לְמֶמְשֶׁ֣לֶת הַלַּ֔יְלָה
The Lesser Light to rule the night
Though the moon is a lesser (Hebrew: קָטָן qatan; small, insignificant) light even when full, it has a significant role in its own domain.
Regardless of its phase, the daily influence of the moon bends the surface of the earth, especially the less dense seas. The gentle pull of its gravity offers assurance that God is still in control of the darkened world.
