And Jeshurun waxeth fat, and doth kick: Thou hast been fat--thou hast been thick, Thou hast been covered. And he leaveth God who made him, And dishonoureth the Rock of his salvation.
Then Jeshurun grew fat, and kicked — Thou art waxen fat, Thou art grown thick, And thou art covered with fatness; — He gave up God who made him, And lightly esteemed the Rock of his salvation.
Meaning in one sentence
Deuteronomy 32:15 meaning: The irony of Jeshurun, God's upright people, who grew fat and kicked. A warning about prosperity leading to forgetfulness.
Context
This verse sits in the Song of Moses, Deuteronomy 32. After leading Israel for forty years, Moses sings a farewell song that God told him to write. It is a witness against the people, predicting what will happen once they settle in the promised land. The first part of the song celebrates God’s perfect care: He found Israel in a desert, protected them like an eagle, fed them honey from rocks and wine from vineyards. Then verse 15 turns. The people God had called upright, Jeshurun, get full and rebel. Moses is not describing something that already happened; he is warning about a pattern as old as humanity. Prosperity can make us forget the hand that fed us.
Key Words
The name 'Jeshurun' appears only four times in Scripture. It comes from a root meaning straight or upright. God was calling His people by a name that described what they were meant to be. Moses uses it here with a heavy edge. They were supposed to be the straight ones, but they went crooked.
The verbs pile up: 'grew fat,' 'grown thick,' 'become sleek.' The Hebrew word for kicked (baat) is what a well-fed animal does when it refuses the yoke. A horse that is full of grain might kick at its master. That is the picture. They did not just stumble into sin. They deliberately pushed back against the One who fed them.
The word for 'abandoned' is natash, a strong word meaning to leave behind or cast off. And they treated 'the Rock of his salvation' with contempt. The word 'Rock' (tsur) echoes verse 4, where God is called the perfect, just Rock. They did not merely neglect Him. They treated Him as something worthless.
How Christians Read This Verse
Reformers like Calvin and Wesley saw here a stark warning: prosperity inflames human pride, and those who have received much often repay God with rebellion. Matthew Henry describes it as 'security and sensuality', the slow drift into self-indulgence that erases gratitude. The Cambridge Bible notes the sarcasm: the name 'Jeshurun' (upright) is applied to a people who have become crooked. Across traditions, Christians agree this is more than a history lesson. It is a mirror held up to every generation that enjoys God’s gifts but forgets the Giver.
A common misunderstanding
Some readers think this verse is only about overeating or physical laziness. In fact, the physical descriptions are metaphors for a deeper spiritual condition. The problem is not that they had plenty; it is that abundance made them self-sufficient. They stopped relying on God. The sin is forgetfulness of the heart, not just a full stomach.
Living This Out
This week, take a quiet look at your life. Where are you most comfortable? Where do you have enough, maybe more than enough? That is exactly the place where forgetfulness creeps in. Gratitude is the antidote. Before you rush into your day, name one good thing God has given you. Let thanks be the reflex before the kick. And if you catch yourself feeling proud or self-reliant, stop and remember the Rock who saved you. He has not changed. You have just grown thick.
Main takeaway: Full bellies and full lives can empty our hearts of gratitude for the God who filled them.
For Families
For ages 5, 8
God gave His people good food and a good land. But they got too full and forgot to say thank you. They even kicked like a stubborn horse. We can remember to thank God every day.
For ages 9, 12
God called His people Jeshurun, which means 'upright one.' But when they had everything they needed, they became proud. They acted like a fat horse that kicks its owner. Moses warned them this would happen. When life is good, it is easy to forget God. That is why gratitude is so important. Every good thing comes from Him. Never let fullness make you forgetful.
