Mark 4:31-32

It is like a mustard seed, which, when it is sown on the ground, even though it is smaller than all the [other] seeds that are [sown] on the soil, yet when it is sown, it grows up and becomes larger than all the garden herbs; and it puts out large branches, so that THE BIRDS OF THE SKY are able to MAKE NESTS and LIVE UNDER ITS SHADE.” [Ps 104:12; Ezek 17:23; 31:6]
