What does Jeremiah 31:32 mean?

It won’t be like the agreement I made with their ancestors when I took them by the hand and led them out of Egypt. They broke that agreement, even though I was like a husband to them, says the Lord. Jeremiah 31:32 - Modern Text Bible

(This new covenant won’t be like the old one that Israel broke. God uses the image of a close, committed relationship to show how deeply He cared.)
