Deuteronomy 6:13 tells Israel to fear the LORD their God, to serve him, and to take oaths only in his name. In plain terms, the verse calls for wholehearted reverence and loyalty toward God, expressed in how they live and how they speak. It is spoken by Moses, who is addressing the people of Israel as they stand on the edge of the promised land.
You shall fear the LORD your God; and you shall serve him, and shall swear by his name.

What Deuteronomy 6:13 Means
The word “fear” here does not mean being frightened of a cruel ruler. It describes a deep, reverent awareness of who God is, a respect that shapes the whole of a person’s life. Fearing the LORD means taking him seriously as the one who made promises, rescued a people from slavery, and holds their future in his hands.
“Serve” points to ongoing devotion rather than a single act of worship. To serve God is to organize daily priorities, habits, and loyalties around him. The verse does not promise prosperity or protection from hardship as a reward for obedience. It describes the posture God’s people are called to take, trusting that his character is worth giving their allegiance to.
The last clause, about swearing by his name, addresses how people speak about what they will do. In the ancient world, invoking a god’s name in an oath was a way of calling that god as a witness. Israel is told to bind their promises to the LORD alone, rather than to the gods of the surrounding nations.
The Context of Deuteronomy 6:13
Deuteronomy is presented as Moses’ farewell speech, delivered on the plains of Moab just before Israel enters Canaan. Traditionally Moses is credited with the book, and its audience is the new generation that grew up in the wilderness rather than the one that left Egypt. The people are about to receive houses, fields, and cities they did not build, and Moses warns them that prosperity can make a person forget the source of their blessings.
The verses just before and after Deuteronomy 6:13 explain why this matters. Verses 10 to 12 describe abundance and then warn against forgetting the LORD who brought them out of Egypt. Verses 14 to 16 forbid following other gods and warn against testing God. Read in this setting, the verse is not a general command about religious feeling. It is a guard against the drift that comes with comfort, when a people might slowly give their loyalty to whatever seems to provide for them.
