Deuteronomy 8:11

9 A land wherein thou shalt eat bread without scarceness, thou shalt not lack any thing in it; a land whose stones are iron, and out of whose hills thou mayest dig brass.

10 When thou hast eaten and art full, then thou shalt bless the LORD thy God for the good land which he hath given thee.

Beware that thou forget not the LORD thy God, in not keeping his commandments, and his judgments, and his statutes, which I command thee this day:

12 Lest when thou hast eaten and art full, and hast built goodly houses, and dwelt therein;

13 And when thy herds and thy flocks multiply, and thy silver and thy gold is multiplied, and all that thou hast is multiplied;

Do read the surrounding verses too, because the context often says more than a single verse.
