In Matthew 6:32, the same teaching appears: your Father knows you need these things, so don't worry like the Gentiles.

In Matthew 23:9, Jesus reinforces that only God in heaven is your Father — consistent with the Father-child relationship assumed in Matthew 6:8.

In Luke 12:30, the same point: the Gentiles seek material things, but your Father knows you need them — identical to Matthew 6:8 about God's prior knowledge.

In Philippians 4:6, Paul echoes the call: instead of anxiety, present your requests to God — consistent with the teaching that God already knows your needs.

In Psalm 38:9, David affirms that God knows all his desires and groans — echoing the truth that God is aware of our needs before we ask.

Romans 8:27 speaks of God knowing the Spirit's mind—paralleling the Father's knowledge of unspoken needs in this verse.
