Old English frogga, a diminutive of frox, forsc, frosc "frog," from Proto-Germanic *fruska-z (cf. Old Norse froskr, Middle Dutch vorsc, German Frosch "frog"), probably literally "hopper," from PIE root *preu- "to hop" (cf. Sanskrit provate "hops," Russian prygat "to hop, jump").
The Latin word (rana) is imitative of croaking. Collateral Middle English forms frude, froud are from Old Norse frauðr "frog," and frosk "frog" survived in English dialects into the 19c.

In the New Testament this word occurs only in Rev. 16:13, where it is referred to as a symbol of uncleanness. The only species of frog existing in Palestine is the green frog (Rana esculenta), the well-known edible frog of the Continent.
