Psalm 139:4 & Heb 4:13: God's knowledge?
How does Psalm 139:4 connect with Hebrews 4:13 about God's knowledge?

The Verses Side by Side

Psalm 139:4: “Even before a word is on my tongue, You know all about it, O LORD.”

Hebrews 4:13: “Nothing in all creation is hidden from God’s sight; everything is uncovered and exposed before the eyes of Him to whom we must give account.”


What Psalm 139:4 Tells Us

• God’s knowledge precedes our speech.

• He knows the full content and intent of every word “before” it comes out.

• The verse highlights a personal, intimate awareness—God knows “my” words, not just humanity’s in general.


What Hebrews 4:13 Adds

• God’s sight is universal: “nothing in all creation” is hidden.

• His knowledge reaches beyond words to thoughts, motives, and deeds.

• The verse introduces accountability: we will “give account” to the One who sees all.


How the Two Passages Interlock

• Omniscience in micro and macro: Psalm 139:4 zooms in on an individual’s words; Hebrews 4:13 zooms out to include every created thing.

• Timing and completeness: Psalm 139:4—God knows before we speak; Hebrews 4:13—God still knows after the fact, with nothing concealed.

• Relationship and responsibility: Psalm 139 emphasizes closeness; Hebrews 4:13 underscores judgment. Together they show God’s knowledge is both relational and forensic.


Supporting Scriptural Threads

Proverbs 15:3: “The eyes of the LORD are in every place, observing the evil and the good.”

1 Samuel 16:7b: “The LORD looks not at the outward appearance, but at the heart.”

1 John 3:20: “If our hearts condemn us, God is greater than our hearts, and He knows all things.”

Job 42:2: “I know that You can do all things and that no purpose of Yours can be thwarted.”

Psalm 147:5: “Great is our Lord, and mighty in power; His understanding has no limit.”


Why This Matters for Daily Life

• Speech discipline: Since God knows our words beforehand, we seek purity of heart so our speech aligns with His holiness (James 1:26).

• Honest living: Nothing is hidden, so integrity must be practiced even when unseen by people (Luke 12:2-3).

• Comfort and courage: The One who knows us this thoroughly also loves us covenant-faithfully (Romans 8:38-39).

• Readiness for account: Awareness of coming evaluation motivates perseverance and obedience (2 Corinthians 5:9-10).


Summing Up

Psalm 139:4 and Hebrews 4:13 together paint a comprehensive portrait of the Lord’s perfect knowledge—personal, exhaustive, and morally significant. Words, motives, and actions all lie open before Him, inviting both reverence and trust as we walk transparently with our all-knowing God.

What comfort can we find knowing 'before a word is on my tongue'?
