John Trapp on Luke 12:29-31

Verse 29. Neither be ye of doubtfull mind] Hang not in suspence, [non-Latin text not transcribed]. as meteors doe in the ayre, not certaine whether to hang or fall to the ground, Meteoradicta volunt quod animos hominum Magir. Physic. suspensos, dubios, et quasi fluctuantes faciant. Aristotle himselfe confesseth, that of some meteors he knew not what to say, though of some other he could say somewhat. One Interpreter renders this word, Make not discourses in the ayre, as the covetous man doth, when his head is tossed with the cares of getting, or feares of losing commodity; Or it may note his endlesse framing of projects for the compassing of his desires. The Syriack rendreth it, Let not your thoughts be distracted about these things. Surely as a clock can never stand still, so long as the plummets hang thereat: so neither can a worldlings heart, for cares and anxieties. These suffer him not to rest night or day; being herein like unto the flyes of Egypt, or those tyrants Esay 16.
