(Fol. 29) MISHNAH: (Ex. 17, 11) And it came to pass when Moses held up his hand, Israel prevailed, etc. Do then the hands of Moses cause war to be waged or to cease? But the passage means to teach this lesson: VThen the Israelites looked upward and pledged their hearts to their Father in heaven, they prevailed; but when they ceased to do so, they failed. We find a similar instance also in (Num. 21, 8) Make unto thee a fiery serpent and set it on a pole, and every one that is bitten, when he looketh upon it shall live. Could, then, the serpent kill or bring to life? But the passage means to teach this lesson: When the Israelites looked upward for aid and pledged their hearts to their Father in heaven, they were healed; but when they did not, they perished.
