Exodus 17:11

And it came to pass, when Moses held up his hand, that Israel prevailed: and when he let down his hand, Amalek prevailed.

Ver. 11. When Moses held up his hand.] The push of Moses's prayers did more than the pikes of all Israel besides. Moses orat et vincit, cessat et vincitur, saith one. Great is the power of prayers. Henricus Anceps, the Emperor of Germany, slew and put to flight a huge army of the Hungarians, his soldiers all crying out with a loud voice, Kyrie eleison; Kyrie eleison! - i.e., Lord, have mercy upon us; Lord, have mercy upon us! This was done before the city of Mersburg. a
