הִֽ֭תְהַלְלוּ בְּשֵׁ֣ם קָדְשׁ֑וֹ יִ֝שְׂמַ֗ח לֵ֤ב ׀ מְבַקְשֵׁ֬י יְהוָֽה׃
Glorifiez-vous de son saint nom; que le cœur de ceux qui recherchent l’Éternel soit en joie!
Rashi on Psalms
Boast of His holy name Boast of the stronghold of His holy name that you have a patron like Him. התהללוּ is “porvontez vous” in Old French, [vantez vous in modern French, boast].
