Old Testament

Mark 4:30-34
Mustard Seed
30Then he said, “To what should we compare the kingdom of God? Or with what parable may we picture it? 31It is like a mustard seed, which when sown on the ground is one of the smallest of all the seeds planted in the ground. 32Yet when it is planted, it grows up and becomes larger than all the garden plants and puts out large branches so that the birds of the sky can nest under its shade.”
33With many similar parables he continued to speak the word to them, as much as they were able to hear. 34He did not speak to them without a parable. But when he was alone with his disciples, he explained everything to them.
