Deuteronomy 6:13

Thou shalt fear the Lord thy God, and serve him, and shalt swear by his name.

Deuteronomy 6:13 (KJV)

Context

This verse belongs to the Shema, the foundational confession of faith in Deuteronomy 6:4-9. The Shema declares that the LORD is one and calls Israel to love Him with the whole heart. Verse 13 follows a warning in verse 12 not to forget the LORD after times of prosperity and deliverance.

Meaning

To “fear the LORD thy God” means deep reverence, awe, and respect for His power, holiness, and authority. It is not paralyzing dread but a filial, reverential affection for the God who freed Israel from slavery in Egypt. This fear acknowledges Him as Creator and Sustainer, deserving our utmost honor.

To “serve him” flows from this fear. It is willing, devoted service in every part of worship, both public and private. The command is exclusive: He alone is to be served, in contrast to the idolatry of surrounding nations. Service includes obedience to His commandments and submission to His will in every area of life.

To “swear by his name” means making oaths and pledges in God’s name with sincerity and integrity. It invokes His authority as witness to the truthfulness of our commitments, binding our word to His character. This is not casual speech but a serious acknowledgment that God is the ultimate judge of truth.

Biblical connections

Jesus quoted this verse when He resisted Satan’s temptation in Matthew 4:10 and Luke 4:8, applying it to worship and service of God alone. This New Testament usage confirms the enduring call to exclusive devotion. The verse’s threefold command—fear, serve, swear—forms a complete picture of covenant loyalty: reverence, service, and truthful witness in God’s name.

Application

Believers today are called to cultivate a deep reverence for God, serve Him faithfully, and live with integrity in promises and relationships. This means honoring God in every area of life, especially when making commitments. The verse reminds us that our relationship with God must shape our daily conduct and our words.

Reflection

Consider how your daily choices reflect reverence for God. Does your service flow from love rather than duty? Are your promises made in His name marked by truthfulness? Let this verse guide you to wholehearted devotion and honest witness.
