"Yet when planted, it grows and becomes the largest of all garden plants, with such big branches that the birds can perch in its shade."
NIV
Yet after it is sown, it grows up and becomes the greatest of all garden herbs and puts out large branches, so that the birds of the air are able to make nests and dwell in its shade.
AMP
But when it is sown, it groweth up, and becometh greater than all herbs, and shooteth out great branches; so that the fowls of the air may lodge under the shadow of it.
