Rabbi Zeira son of Rabbi Abbahu expounded: From where [do we learn] that one does not recite the blessing over the lamp on Motzoei Shabbos until one has benefited from its light? As it is written “And God saw the light that it was good” and afterward “and He separated.”
On the daf / in context: The Yerushalmi derives the practical requirement of benefiting from the light before blessing it from the sequence in the passuk: first “saw that it was good,” then the separation.
Type of Learning: Sequence for blessing on the light (Motzoei Shabbos)What Is Learned: One must derive benefit from the Havdoloh candle before reciting the blessing over it, following the order of “seeing the light that it is good” before separation.
