Deuteronomy 31:16 And Jehovah said unto Moses, Behold, thou shalt sleep with thy fathers; and this people will rise up, and play the harlot after the strange gods of the land, whither they go to be among them, and will forsake me, and break my covenant which I have made with them.
Deuteronomy 31:17 Then my anger shall be kindled against them in that day, and I will forsake them, and I will hide my face from them, and they shall be devoured, and many evils and troubles shall come upon them; so that they will say in that day, Are not these evils come upon us because our God is not among us?

The verse centers on "jehovah", "said", "moses", "behold", "thou", "shalt", "sleep", and "fathers". It is saying that the verse draws attention to "jehovah" and "said", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 15's "And Jehovah appeared in the Tent in..." into verse 17's "Then my anger shall be kindled against...", so "jehovah" and "said" belong inside that flow. In Deuteronomy context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "jehovah" and "said" with trust shaped by these words, not by a vague optimism outside the passage.
