Matthew 13:31-32
31 He presented another parable to them: “The kingdom of heaven is like a mustard seed that a man took and sowed in his field. 32 It’s the smallest of all the seeds, but when grown, it’s taller than the vegetables and becomes a tree, so that the birds of the sky come and nest in its branches.”
Mark 4:30-34
30 And He said: “How can we illustrate the kingdom of God, or what parable can we use to describe it? 31 It’s like a mustard seed that, when sown in the soil, is smaller than all the seeds on the ground. 32 And when sown, it comes up and grows taller than all the vegetables, and produces large branches, so that the birds of the sky can nest in its shade.”
33 He would speak the word to them with many parables like these, as they were able to understand. 34 And He did not speak to them without a parable. Privately, however, He would explain everything to His own disciples.
Luke 13:18-19
18 He said, therefore, “What is the kingdom of God like, and what can I compare it to? 19 It’s like a mustard seed that a man took and sowed in his garden. It grew and became a tree, and the birds of the sky nested in its branches.”
