You are to fear the LORD your GodThe command to fear the LORD is a central theme in Deuteronomy and the entire Old Testament. This fear is not about terror but reverence and awe for God's holiness, power, and authority. In the ancient Near Eastern context, fear of a deity was common, but the Israelites were called to a unique relationship with Yahweh, characterized by love and obedience. This fear is foundational to wisdom (
Proverbs 9:10) and is the beginning of knowledge (
Proverbs 1:7). It reflects a deep respect and acknowledgment of God's sovereignty and justice.
and serve Him.
Service to God in the Old Testament often involved worship, sacrifices, and obedience to His commandments. The Hebrew word for "serve" can also mean "worship," indicating that true service to God is an act of worship. This service is exclusive, as seen in the first commandment (Exodus 20:3), and is a response to God's deliverance and covenant relationship with Israel. Jesus reiterates this principle inMatthew 4:10, emphasizing that worship and service are due to God alone.
Hold fast to Him
Holding fast to God implies loyalty and commitment. In the covenantal context, it means clinging to God and His commandments, rejecting idolatry and other allegiances. This phrase suggests a relationship akin to a marriage, where faithfulness and devotion are paramount.Joshua 23:8 echoes this sentiment, urging Israel to cling to the LORD as they had done in the past. It is a call to steadfastness in faith and practice.
and take your oaths in His name.
Oaths in the ancient world were serious commitments, often invoking a deity as a witness to the truth of one's words. By instructing the Israelites to take oaths in God's name, the text underscores the importance of truthfulness and integrity. It also highlights the exclusivity of their relationship with Yahweh, as oaths were not to be made in the names of other gods. Jesus later addresses the issue of oaths inMatthew 5:33-37, emphasizing honesty and the importance of one's word without the need for swearing by anything.

You are to fear the LORD your God“Fear” here is reverent awe that rejects casual familiarity and embraces God’s holiness.
•Proverbs 1:7 notes that “The fear of the LORD is the beginning of knowledge,” underlining that true wisdom starts with humble recognition of His supremacy.
• Moses has already said, “Fear the LORD your God, serve Him only” (Deuteronomy 6:13). This passage repeats that call, showing it is foundational, not optional.
•Psalm 111:10 connects fear with obedience, whileHebrews 12:28-29 reminds believers that God remains “a consuming fire,” worthy of trembling respect.
Living in this fear means confessing sin quickly, approaching worship seriously, and patterning every decision around God’s revealed character.
and serve HimTo serve (ʿābad) is to worship, work, and obey under God’s rule.
• Joshua urges, “Serve Him with all faithfulness” (Joshua 24:14-15), linking service with wholehearted loyalty.
•Romans 12:1 expands the idea: presenting our bodies “as a living sacrifice” is “your spiritual service of worship.”
•Colossians 3:23-24 shifts service beyond church walls: “Whatever you do, work at it with all your heart… It is the Lord Christ you are serving.”
Practical outflow:
– Sunday worship becomes a weekly recalibration.
– Weekday tasks, from spreadsheets to toddlers, are re-defined as offerings to God.
– Ministry, generosity, and neighbor-love turn into acts of grateful service, not self-promotion.
Hold fast to Him“Hold fast” pictures gripping tightly and refusing to let go, just as a vine clings to a trellis.
•Deuteronomy 11:22 promises blessing “if you carefully keep all these commandments… and cling to Him.”
•Joshua 23:8 urges Israel to “hold fast to the LORD your God as you have until now,” guarding against drift.
• Jesus amplifies the image: “Remain in Me, and I will remain in you” (John 15:4-5). Abiding, not periodic visits, produces fruit.
To hold fast is to:
– Nourish daily communion through Scripture and prayer.
– Reject alliances or habits that loosen your grip (2 Corinthians 6:17).
– Persevere through trial, convinced that “He Himself has said, ‘I will never leave you nor forsake you’” (Hebrews 13:5).
and take your oaths in His name.Oaths invoke God as the guarantor of truth. Israel was to swear only by the LORD, never by other gods (Deuteronomy 6:13).
•Isaiah 45:23 shows God Himself taking an oath, underscoring the practice’s gravity.
•Hebrews 6:16 observes that oaths “end all dispute,” recognizing their legal weight.
• Jesus cautions empty oath-making (Matthew 5:33-37), andJames 5:12 tells believers to let “Yes” be yes, because every word already lies before God.
Principles today:
– Speak truth consistently so formal oaths become unnecessary.
– If civil settings require oaths, invoke God’s name with sober integrity.
– Never use His name to mask deceit; He will not hold the liar guiltless (Exodus 20:7).
summaryDeuteronomy 10:20 stitches together four inseparable responses to God’s covenant mercy: revere Him, serve Him, cling to Him, and honor His name with truthful speech. Each phrase pushes the heart beyond mere rule-keeping toward a life saturated with worship, obedience, loyalty, and integrity. Stand in awe, work for His glory, stay near, and speak honestly—this is what it means to live as His redeemed people.
(20)
Thou shalt fear the Lord thy God; him shalt thou serve.--In the New Testament, "Thou shalt
worshipthe Lord thy God, and him
onlyshalt thou serve." It was our Lord's last answer to the tempter in the wilderness. The order of the Hebrew gives the emphasis. "Jehovah thy God shalt thou fear, Him shalt thou serve, and to Him shalt thou cleave;" "and (adds Rashi) after all these qualities are established in thee,
then thou shalt swear by His name."At least His name would not be profaned in such a case.
Verse 20. - Reverting to his main theme, Moses anew exhorts Israel to fear Jehovah their God, and to show true reverence to him by serving him, by cleaving to him, and by swearing in his Name (cf.
Deuteronomy 4:4;
Deuteronomy 6:13;
Acts 11:23). Such reverence was due from Israel to God, because of the great things he had done for them, and those terrible acts by which his mighty power had been displayed on their behalf.
