Psalms 139:4

For there is not a word in my tongue, but, lo, O Lord, thou knowest it altogether.

Psalms 139:4 (KJV)

Context

Psalm 139 is a personal song written by King David. It celebrates God’s complete knowledge, His presence everywhere, and His power over all things. In this verse, David declares that God knows every word he speaks, even before the words are formed on his tongue.

Meaning

David begins by saying there is not a word in his tongue that God does not know. The phrase “thou knowest it altogether” means God understands each word fully, including its meaning, its tone, and the intention behind it. This is not distant knowledge; it is intimate and personal. God knows David’s words completely, and He knows ours in the same way.

This truth shows God’s omniscience, His perfect knowledge of all things. It also reveals His care. God does not merely hear our words; He understands the heart from which they come. Even when we cannot express ourselves clearly, God knows exactly what we mean. His knowledge covers our thoughts and intentions, not just our speech.

Biblical connections

God’s readiness to hear His people is seen in Isaiah 65:24, where He promises to answer before they call. Similarly, Malachi 3:16 describes God listening to those who fear Him. These passages, like Psalm 139:4, show that God is not distant but attentive to the words of His people. In the New Testament, Christ also demonstrated this knowledge. In Luke 19:31-33, He knew what the owners of the colt would say before they spoke. This confirms that God’s knowledge of our words is consistent throughout Scripture.

Application

Because God knows every word before we speak it, we are called to be honest and accountable in our speech. We should avoid lies, gossip, and hurtful words, and instead speak truth in love. Knowing that God hears us also encourages us to pray with confidence, trusting that He understands our needs even before we ask.

We can also find comfort in God’s knowledge. When others misunderstand us, God does not. He sees the intentions of our hearts and knows the meaning behind our words. This assurance allows us to rest in His understanding and to seek His guidance in all our conversations. His knowledge of our private conversations and prayers reassures us of His constant presence and care.

Reflection

David responds to God’s knowledge with wonder, saying in verse 6 that such knowledge is too wonderful for him. Like David, we can stand in awe of a God who knows us so deeply. His perfect knowledge is not a threat but a comfort, for it flows from His love and care for us. This recognition inspires reverence and trust in His sovereign knowledge.
