Luke 13:18-21

So this led Him to say, “What is the kingdom of God like? And to what shall I compare it? [Matt 13:31, 32; Mark 4:30-32] It is like a mustard seed, which a man took and planted in his own garden; and it grew and became a tree, and THE BIRDS OF THE SKY FOUND SHELTER and NESTED IN ITS BRANCHES.” [Ezek 17:23; Dan 4:12] And again He said, “To what shall I compare the kingdom of God? It is like leaven, which a woman took and hid in three peck measures of flour until it was all leavened.” [Matt 13:33]
