Deuteronomy 8:19 Meaning and Commentary

Deuteronomy 8:19

And it shall be, if thou do at all forget the Lord thy God,
&c.] Either the mercies they received from him, not acknowledging they came from him, but ascribing them to themselves; or their duty to him, to whom they were so greatly obliged: and walk after other gods, and serve them, and worship them; which would be to forget him indeed, forsaking his worship, and giving homage and adoration to idols, which is what is intended by these expressions:

I testify against you this day that ye shall surely perish;
by one judgment and calamity or another, as the sword, famine, pestilence, and captivity; there being nothing more provoking to God than idolatry, which so much detracts from his honour and glory: and which besides, in such a people, so highly favoured of God, it argued the basest ingratitude.

Deuteronomy 8:19 In-Context

17 And you may think in your heart, 'My strength and the might of my hand {acquired this wealth for} me.'

18 But you must remember Yahweh your God, for he [is] the [one] giving you strength to acquire wealth in order to confirm his covenant that he swore to your ancestors {as it is today}.

19 And it will happen [that] if you indeed forget Yahweh your God and you go after other gods and you serve them and you bow down before them, I warn you today that you will surely perish.

20 As [with] the nations that Yahweh [is] destroying {before you}, so you shall perish because you would not obey the voice of Yahweh your God.
