Parallel
Psalms 133:2
Westminster Leningrad Codex · Berean Standard Bible
כַּשֶּׁ֤מֶן הַטּ֨וֹב׀ עַל־ הָרֹ֗אשׁ יֹרֵ֗ד עַֽל־ הַזָּקָ֥ן זְקַֽן־ אַהֲרֹ֑ן שֶׁ֝יֹּרֵ֗ד עַל־ פִּ֥י מִדּוֹתָֽיו׃
It is like fine oil on the head, running down on the beard, running down Aaron’s beard over the collar of his robes.
