Groweth up (anabainei). Matthew 13:32When it is grown (otan auxhqh). Under the shadow thereof (upo thn skian autou). A different picture from Matthew's in the branches thereof (en toi kladoi autou). But both use kataskhnoin, to tent or camp down, make nests in the branches in the shade or hop on the ground under the shade just like a covey of birds. In Matthew 8:20 the birds have nests (kataskhnwsei). The use of the mustard seed for smallness seems to have been proverbial and Jesus employs it elsewhere ( Matthew 17:20 ; Luke 17:6 ).
