figs are not gathered from thorns; nor are grapes picked from a bramble bush

The Greek that is translated in English as “figs are not gathered from thorns, nor are grapes picked from a bramble bush” or similar is translated in Upper Guinea Crioulo as “You wouldn’t pick guavas [very similar to figs] from a thorn bush, or cashews from a thorn tree.” (Source: David Frank in this blog post)
