Romans 11:22
So, look at God's kindness and severity. He was severe with those [Jews] who have fallen, but He is kind to you [Gentiles], if you continue to accept His kindness [i.e., by living for Him faithfully]. Otherwise, you too will be cut off [like the Jews were].
1 Corinthians 10:5-6
However, God was not pleased with the vast majority of them, for their bodies were scattered over the desert [See Num. 14:29ff].
Hebrews 3:17-18
And who was God angry with for forty years? Was it not with those people who sinned, whose bodies fell [dead] in the desert?
Jude 1:5
But, I want to remind you, [even] though you already know the stories about how the Lord delivered His people from Egyptian [bondage], and then [later] destroyed those who did not believe [in Him].
