'Warnings' in the Bible

They rejected the LORD's statutes, the covenant that he had made with their ancestors, and his warnings that he gave them. They pursued meaninglessness and became meaningless themselves as they followed the lifestyles of the nations that surrounded them, a practice that the LORD had warned them not to do.

Furthermore, neither our kings, nor our leaders, nor our priests nor our ancestors have practiced your Law or paid attention to your commands and warnings by which you admonished them.

I will display warnings in the heavens, and on the earth blood, fire, and columns of smoke.
