Context
Psalm 104 is a song that walks through the days of creation, from light to the creatures of the sea. By verse 19 the poet has described the rain on the mountains and now turns to the lights in the sky. He is not writing a science textbook, but a hymn of wonder. The moon and sun appear here not as gods, the surrounding nations worshiped them, but as humble servants. They do what they were made to do. The next verses will show night falling, animals stirring, and then morning coming again. Everything runs on a rhythm the Creator set.
Key Words
Three Hebrew words open the verse. The first, asah, means simply ‘he made.’ No ceremony. God did this. The moon is yareach, and the word God gave it is moed, ‘appointed times.’ The same word is used for sacred festivals. The moon does not just shine. It calls the people to gather, to celebrate, to remember.
Then the sun. The poet says it yada: it ‘knows’ its going down. That word is usually used for people. Adam knew Eve. God knew Israel. It means deep, personal awareness. The sun does not stumble into the evening. It knows exactly where it is going, because it trusts the One who set the horizon.
How Christians Read This Verse
Christians across traditions agree that this verse calls us to wonder, not worship the sun and moon. Adam Clarke and Matthew Henry both highlight that nearby nations bowed to these lights, but the psalmist puts them under God’s authority. Keil and Delitzsch note that the poet follows the order of the creation days, the moon comes first because the writer is about to describe the night. Barnes adds that the ‘seasons’ include sacred festivals ordered by the moon. The differences are about emphasis: some stress that this refutes astrology, others that it grounds the Sabbath week in creation. All see a God who loves order and shares it with us.
A common misunderstanding
Some read ‘the sun knows its going down’ as mere poetry, a fancy way to say the sun sets on time. In fact, the Hebrew word yada means intimate, obedient knowledge. The sun is not a machine; it is a willing servant. It knows its place and keeps it, not by blind force but as a conscious creature responding to its Maker.
Living This Out
This week, notice the sunset. You might watch it slip below the horizon at a different minute each evening. But the sun is not lost. It knows exactly when to set because God appointed the time. You may feel your own days are unpredictable, work deadlines, family needs, health questions. But the same God who set the sun’s path has appointed your seasons too. You can trust His timing even when you cannot see the whole sky.
Main takeaway: God appointed the moon and sun to mark our times, and they obey Him faithfully, so we can trust His order for our days.
For Families
For ages 5, 8
God made the moon to tell us when it is time for holidays. He made the sun to know exactly when to go to bed at night. We can trust God to keep everything on time.
For ages 9, 12
This verse says the sun ‘knows’ when to set, like it is a person. The Hebrew word means the sun is not just following a rule; it willingly obeys God. The moon marks seasons for festivals. Every month and every night is a reminder that God has a plan for time. Your days are not random, God has a purpose for them too.
Questions People Ask

Does this verse teach that the sun and moon are alive?
