"Behold, I come quickly: blessed is he that keepeth the sayings of the prophecy of this book."
Rev 22:7
 
This is John's verse for today, and it struck me to look up the word "keepeth" in Strongs. Greek # 5083, teros, meaning a watch, perhaps akin to 2334 TO DISCERN; also to guard ( from loss or injury by keeping the eye upon)i.e. to note (a prophecy; fig. to fulfill a command); by implication, to detain (in custody, fig. to maintain); by extension to withhold (for personal ends; fig. to jkeep unmarried);- hold fast, keep, serve, watch.
