Paul Makes Up Proverbs

Luke records that when Paul spoke to the Ephesian elders he said, I have shewed you all things, how that so labouring ye ought to support the weak, and to remember the words of the Lord Jesus, how he said, It is more blessed to give than to receive.^{Acts 20:35}

A wonderful proverb, but Jesus is not recorded in the gospels as ever saying, "It is more blessed to give than to receive." The closest we get is when Jesus was sending out his twelve apostles to preach the Kingdom, he said, And as ye go, preach, saying, The kingdom of heaven is at hand. Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.^{Matthew 10:7, 8}

Even here, Jesus did not say that it is more blessed to give than to receive. So, why did Paul make up a quote from Jesus? If this was a specific quote given specifically to Paul, then why did Jesus choose not to share it?

Value of this Evidence

This is decent evidence for Paul being a false apostle. We would expect false apostles to make up commands and proverbs Jesus did not say.
