The sky is red and lowering - The signs of fair and foul weather were observed in a similar manner among the Romans, and indeed among most other people. Many treatises have been written on the subject: thus a poet: -

Caeruleus pluviam denunciant, Igneus euros

Sin Maculae incipient Rutilo immiscerier Igni,

Omnia tunc pariter Vento Nimbisque videbis

Fervere Virg. Geor. i. l. 453

"If fiery red his glowing globe descends,

High winds and furious tempests he portends:

But if his cheeks are swoll'n with livid blue,

He bodes wet weather, by his watery hue

If dusky spots are varied on his brow,

And streak'd with red a troubled color show,

That sullen mixture shall at once declare,

Wind, rain, and storms, and elemental war

Dryden.

And in the morning, it will be foul weather today,.... When you rise in the morning, and take a survey of the heavens, it is a very usual thing with you to say, it is like to be windy or rainy weather today,

for the sky is red and lowring; which shows, that the clouds are so thick that the sun cannot pierce through them, and its face is not seen; so that it may be reasonably concluded they will issue in rain, or wind, or both.

O ye hypocrites. The Vulgate Latin, and Munster's Hebrew Gospel, leave out this appellation; but all other versions, as well as copies, have it: and it is an usual epithet, bestowed very justly by Christ, on these men; who pretended to be the guides of the people, took upon them to teach and instruct them in divine things, and set up themselves as men of great holiness, piety and knowledge; and yet, instead of searching the Scriptures, and comparing the characters of the times of the Messiah therein fixed, with the present ones, spent their time in making such low and useless observations, and which fall within the compass of everyone's knowledge and reach.

Ye can discern the face of the sky; very distinctly, and make some very probable guesses, if not certain conclusions, what will follow, good weather or bad:

but can ye not discern the signs of the times? or, as the Syriac reads it, "the time", the present time: if they had not been blind, they might easily have discerned, that the signs of the time of the Messiah's coming were upon them, and that Jesus was the Messiah; as the departure of the sceptre from Judah, the ending of Daniel's weeks, the various miracles wrought by Christ, the wickedness of the age in which they lived, the ministry of John the Baptist, and of Christ, the great flockings of the people, both to one and to the other, with divers other things which were easy to be observed by them: but they pretend this to be a very great secret.

"The secret of the day of death, they say (y), and the secret of the day when the king Messiah comes, who by his wisdom can find out?''

(y) Targum in Ecclesiastes 7.24.

Lowering (στυγνάζων)

The verb means to have a gloomy look. Dr. Morison compares the Scotch gloaming or glooming. Cranmer, the sky is glooming red. The word is used only here and at Mark 10:22, of the young ruler, turning from Christ with his face overshadowed with gloom. A.V., he was sad. Rev., his countenance fell.

And in the morning, It will be foul weather to day: for the sky is red and lowring. O ye hypocrites, ye can discern the {b} face of the sky; but can ye not discern the signs of the times?

(b) The outward show and countenance, as it were, of all things, is called in the Hebrew language, a face.

16:3 Can ye not discern the signs of the times. They could read the weather, but were blind to the events (signs of the times) that showed the fulfillment of prophecy, the end of the Jewish dispensation, and the establishment of the Messiah's kingdom.

16:3 The signs of the times - The signs which evidently show, that this is the time of the Messiah.

16:1-4 The Pharisees and Sadducees were opposed to each other in principles and in conduct; yet they joined against Christ. But they desired a sign of their own choosing: they despised those signs which relieved the necessity of the sick and sorrowful, and called for something else which would gratify the curiosity of the proud. It is great hypocrisy, when we slight the signs of God's ordaining, to seek for signs of our own devising.
