and thou forget the Lord thy God;

which brought thee forth out of the land of Egypt, from the house of
bondage;
into a land abounding with all the above good things, and therefore it must be the highest ingratitude to forget such a God, and disobey his commands.

Deuteronomy 8:14 In-Context

12 lest thou eat, and hast been satisfied, and good houses dost build, and hast inhabited;

14 `And thy heart hath been high, and thou hast forgotten Jehovah thy God (who is bringing thee out of the land of Egypt, out of a house of servants;
15 who is causing thee to go in the great and the terrible wilderness -- burning serpent, and scorpion, and thirst -- where there is no water; who is bringing out to thee waters from the flinty rock;
16 who is causing thee to eat manna in the wilderness, which thy fathers have not known, in order to humble thee, and in order to try thee, to do thee good in thy latter end),
