Lexical Definition

‎ῥίπτω‎ rhíptō (hrip'-to) to throw/lay down ^G:V
a primary verb (perhaps rather akin to the base of ‎ῥαπίζω‎, through the idea of sudden motion)

cast (down, out), scatter abroad, throw.

• to fling (properly, with a quick toss, thus differing from ‎βάλλω‎, which denotes a deliberate hurl
• and from (see in ‎ἐκτείνω‎), which indicates an extended projection)
• by qualification, to deposit (as if a load)
• by extension, to disperse
