What does the Bible say about Old Testament covenants?

In the Old Testament, God established covenants with His people, specifically through national Israel. These covenants were meant to demonstrate God's faithfulness and desire for a relationship with His people. However, Israel repeatedly broke these covenants, as highlighted in passages like Jeremiah 31:31-34, which prophesies a new covenant that God would establish to replace the old covenant, highlighting the inherent weaknesses of the previous agreements due to human sinfulness. The breaking of these covenants illustrates the need for a true and everlasting covenant, fulfilled in Christ.
