'Birds of the Air' in the Bible

Jesus replyed, the foxes have kennels, and the birds of the air have nests; but the son of man hath not where to lay his head.

'tis one indeed of the smallest grains: but when it is grown, it is the largest of the pulse kind, and becomes a tree: so that the birds of the air come and lodge in its branches.

Jesus answered him, foxes have their kennels, and birds of the air their nests, but the son of man hath not where to lay his head.

it is like a grain of mustard-seed, which a man took, and sowed in his garden: it grew, and became so large, that the birds of the air built their nests in its boughs.
