Luke 6:44 For each tree is known by its own fruit. For people don't gather figs from thorns, nor do they gather grapes from a bramble bush. (See NAS)
Micah 7:4 The best of them is as a briar; the most upright, worse than a thorn-fence. The day of thy watchmen, thy visitation is come; now shall be their perplexity. (DBY NAS)
