how does this teaching relate to old testament warnings against idolatry?

Adds the setting and its conversation across both testaments.

Matthew 6:24

“No one can serve two masters; for either he will hate the one, and love the other; or else he will be devoted to one, and despise the other. You cannot serve God and Mammon.”

This passage is part of Jesus' Sermon on the Mount, a collection of his teachings on discipleship and the nature of God's kingdom. Here, he is addressing concerns about material wealth and priorities in life.

Then — the setting

This teaching from Jesus' Sermon on the Mount (likely delivered around 30-33 CE in Galilee) addresses his Jewish audience who were familiar with a long tradition of warnings against idolatry. While 'Mammon' (μαμμωνᾶς, *mammōnás*) specifically refers to wealth or money, it's personified here as a rival master. For a society where economic survival was often precarious and wealth could be seen as a source of security, Jesus's words challenged their fundamental allegiances, linking financial devotion to spiritual devotion.

Across the Testaments

The Old Testament is replete with warnings against idolatry, primarily concerning the worship of pagan gods like Baal or Asherah (e.g., Exodus 20:3; Deuteronomy 6:14). These were often tangible idols representing rival spiritual powers. Jesus' teaching in Matthew 6:24 deepens this by identifying 'Mammon'—wealth itself—as a potential rival 'master.' While not a carved image, the pursuit and security of wealth can demand allegiance and trust that rightly belong to God alone, thus functioning as an idol in practice. The New Testament extends the concept of idolatry beyond physical statues to include anything that takes God's place in one's life, such as greed (Colossians 3:5).
