Deuteronomy 29:9

That ye may prosper in all that ye do. The verb here used ( הִשְׂכִּיל ) means primarily to look at, to consider or attend to, hence to become intelligent, to be prudent, to act wisely, and so to have success, to prosper. It is the prosperity which comes from wise and prudent action that God commends to his people (cf. Joshua 1:7 , Joshua 1:8 ).
