may the power of my Lord be magnified
Moses is asking for God's power to be displayed, not for personal gain, but for the glory of God. This reflects the biblical theme that God's strength is made perfect in weakness (2 Corinthians 12:9). The term "Lord" here is a reference to Yahweh, emphasizing a personal relationship and covenant with God. The magnification of God's power is a recurring theme, seen in the deliverance of Israel from Egypt and the miracles in the wilderness.

just as You have declared
Moses reminds God of His own words, showing the importance of God's promises and faithfulness. This phrase underscores the reliability of God's word, as seen in Isaiah 55:11, where God's word does not return void. It also reflects the covenantal relationship where God’s declarations are binding and trustworthy. Moses is invoking God's past declarations of mercy and forgiveness, as seen earlier in Exodus 34:6-7, where God describes Himself as compassionate and gracious.

Moses has just heard the LORD’s judgment on Israel’s unbelief (Numbers 14:11-16). He does not argue that the people deserve mercy; instead, he immediately turns to prayer.

• “So now” signals urgency—much like Exodus 32:11-13, when Moses interceded after the golden calf.

• Intercession flows from confidence that God hears His covenant people (James 5:16; 1 John 5:14).

• Moses approaches boldly yet humbly, illustrating Hebrews 4:16 long before it was written: “Let us then approach the throne of grace with confidence.”

Prayer, then, is the first and best response whenever judgment is deserved but mercy is desired.

The request centers on God’s “power”—not human ability. Scripture consistently portrays this power as:

• Creative (Genesis 1:3; Isaiah 40:26)

• Redemptive (Exodus 15:6; Jeremiah 32:17)

• Sustaining (Colossians 1:17)

Calling God “my Lord” personalizes the plea; Moses trusts the LORD he knows from the burning bush (Exodus 3:6). He believes divine power is sufficient to forgive and restore, just as later believers rely on “the surpassing greatness of His power toward us who believe” (Ephesians 1:19).

To magnify God’s power is to make it visible and admired among people, much like Psalm 34:3, “Magnify the LORD with me.”

• God’s power is already infinite; the prayer asks that it be displayed so unmistakably that Israel—and the watching nations (Numbers 14:13-14)—cannot miss it.

• Every act of mercy enhances God’s reputation, showing He is both mighty and gracious (Psalm 145:8-12).

• When believers today testify to answered prayer, they likewise “make His deeds known among the peoples” (Isaiah 12:4).

Moses anchors his request in God’s own words, echoing Exodus 34:6-7, where the LORD proclaimed Himself “abounding in loving devotion and faithfulness, maintaining loving devotion to a thousand generations, forgiving iniquity.”

• Appealing to God’s self-revelation is a model of faith: what God has spoken, He will do (Numbers 23:19; Isaiah 55:11).

• By quoting the LORD back to Himself, Moses highlights divine consistency—God’s character does not change (Malachi 3:6; James 1:17).

• This approach teaches us to pray Scripture, aligning our desires with God’s promises (John 15:7).

Numbers 14:17 records Moses’ urgent, Scripture-saturated plea: he prays immediately, trusts the LORD’s limitless power, longs for that power to be publicly honored, and grounds every word in what God has already said about Himself. The verse invites believers to intercede with the same confidence—knowing that when we ask God to act according to His declared character, His magnified power brings mercy, maintains His reputation, and strengthens faith for all who witness it.
