(found on another paper) Pres T[aylor]. said he obtained his endowment in Nauvoo along with the others of the Twelve and their wives under the direction of Prophet Joseph in the year 1843 in the room over the store and before the temple was finished. He also related a circumstance of having met the Prophet Joseph when the principal of the revelation on celestial marriages was revealed and had been talked about some. The Prophet was on horseback riding into town having been on horseback riding into a meeting on meeting me we passed the compliment of the day when the Prophet said "These things must be accepted and entered into, for they cannot be trifled with and the Keys will soon be turned unless they are accepted." These remarks set me to thinking and I soon took steps in accordance therewith.
