Deuteronomy 6:13 tells God’s people to fear the LORD, serve him, and make their oaths in his name alone. Moses speaks these words to the Israelites as they stand on the edge of the promised land, preparing to enter a place full of blessings they did not earn.
You shall fear the LORD your God; and you shall serve him, and shall swear by his name.

What Deuteronomy 6:13 Means
The verse gives three commands that work together. To “fear the LORD your God” means to hold him in deep reverence, to take seriously who he is and what he has done. This is not the cringing dread of someone expecting punishment, but the settled awe of a person who knows they are dealing with a holy and faithful God.
To “serve him” means to live as his servant. In the ancient world, a servant belonged to a master and organized daily life around that master’s will. Moses is saying that Israel’s ordinary choices, not only their worship services, should belong to the LORD.
The last command, to “swear by his name,” means that when Israelites made solemn promises, they were to call on the LORD as their witness rather than on other gods or on their own cleverness. The verse does not promise that obedience will make life easy or guarantee specific outcomes. What it does promise is that the LORD is worthy of this kind of loyalty, and that people who give it are steering their lives toward the one who made them.
The Context of Deuteronomy 6:13
Deuteronomy is presented as a series of speeches Moses gave to Israel near the end of their forty years in the wilderness. Traditionally Moses is named as the author, and the audience is the new generation who will cross the Jordan River into Canaan. Many of them were children when their parents left Egypt, so Moses is reminding them of the story they inherited and calling them to make it their own.
The verses just before this one, in Deuteronomy 6:10-12, describe a future of abundance: cities they did not build, houses full of goods they did not fill, and vineyards they did not plant. Moses warns that prosperity is the very moment people are most likely to forget the LORD who rescued them from slavery. That warning is why the command to fear and serve him comes right after it. Read this way, the verse is not a demand made in a time of hardship but a safeguard for a time of comfort.
Key Phrases in Deuteronomy 6:13
Matthew 4:10
Then Jesus said to him, “Get behind me, Satan! For it is written, ‘You shall worship the Lord your God, and you shall serve him only.’”

When Jesus quotes this command to the devil in the wilderness, he uses the same language of worshiping and serving God alone. The passage shows that this call to exclusive loyalty stands at the heart of Christian faith, and that Jesus himself lived by it under the strongest pressure.
Joshua 24:15
If it seems evil to you to serve the LORD, choose today whom you will serve; whether the gods which your fathers served that were beyond the River, or the gods of the Amorites, in whose land you dwell; but as for me and my house, we will serve the LORD.”

Joshua gives Israel a similar choice at the end of his life, urging them to decide whom they will serve. His words echo Moses’ call to serve the LORD wholeheartedly, and they show how this commitment is made personal through a decision the people must choose for themselves.
A Short Prayer From Deuteronomy 6:13
Lord, you are worthy of my reverence and my service. Help me to fear you as the one who has rescued me and holds my future, not out of dread but out of a settled awe that shapes my choices. Teach me to serve you in the ordinary places of my life, at work, at home, and in the quiet moments no one else sees. When I make promises, let my words be faithful, spoken in your presence and kept for your glory. Amen.
