Deuteronomy 29:9
Keep therefore the words of this covenant, and do them, that ye may prosper in all that ye do. (Deuteronomy 29:9)
Prosper.
 Literally, “show oneself attentive to,” “act circumspectly,” “manifest prudence.” It refers more to wise management, to showing oneself skillful in all one’s personal affairs (see Deut. 32:29; Joshua 1:8; Ps. 101:2; Dan. 12:3).
