וְהַחַיּ֖וֹת רָצ֣וֹא וָשׁ֑וֹב כְּמַרְאֵ֖ה הַבָּזָֽק׃
那些活物來回奔走，快如閃電的樣子。
Chagigah
"(Ezekiel 1:14) And the Chayot [were] running and returning, like the appearance of a flash." What is "running and returning"? Rav Yehudah said: "Like the light that goes out of the mouth of the furnace." What is "Like the appearance of a flash"? Rabbi Yossi the son of Chanina said, "Like the light that goes out from between the potsherds."
