Day 192-11

Psa 50:21  These things hast thou done, and I kept silence; thou thoughtest that I was altogether such an one as thyself: but I will reprove thee, and set them in order before thine eyes.

I initially took this verse to be a rebuke for attempting to see God as on the same level/ability as man.  Gill's take on it:

These things hast thou done,.... "These evil works", as the Targum; which they had done over and over again without remorse, with the greatest pleasure, and with promises of impunity to themselves. This is a confirmation of the charge made by the omniscient God, who saw and knew all their actions; 

and I kept silence; spoke not by terrible things in righteousness, deferred the execution of judgment, exercised forbearance and patience, and gave space to repent; which being despised, they were hardened yet more and more in sin; see Ecc_8:11. This refers to the space of time between the crucifixion of Christ and the destruction of Jerusalem; 

thou thoughtest that I was altogether such an one as thyself; either that he did not see the things committed by them in secret, as the things before mentioned, theft, adultery, slander, and detraction, commonly are; because they could not see such actions done by others: or that he took pleasure in them, as they did, and that he approved of their crucifixion of Jesus of Nazareth, and of their contempt of his Gospel, and of the persecution of his followers; 

but I will reprove thee: not verbally by the ministry of the word, much less effectually and savingly by his Spirit; nor in a way of fatherly correction and chastisement; but by sore judgments; by sending the Roman armies to burn their city and temple, and carry them captive; 

and set them in order before thine eyes; that is, their sins, and thereby fully confute their vain imagination, that either he did not take notice of them, or else approved of them. This signifies a formal process against them, as in a court of judicature; bringing in a regular charge and accusation against them, and an orderly disposition of their sins, as to time, place, and circumstances, committed by them, and a strong evidence or thorough conviction of them, so as not to be denied and gainsaid by them: or a setting them in battle array, as in Job_6:4; in rank and file; sins being what war against men, and bring upon them utter ruin and destruction; as the sins of the Jews fought against them, and destroyed them; see Jer_2:19.

K&D:

The sinner thinks otherwise: God is like himself, i.e., that is also not accounted by God as sin, which he allows himself to do under the cloak of his dead knowledge. For just as a man is in himself, such is his conception also of his God (vid., Psa_18:26.). But God will not encourage this foolish idea: “I will therefore reprove thee and set (it) in order before thine eyes” (וְאֶֽעֶרְכָה, not ואערכֶהָ, in order to give expression, the second time at least, to the mood, the form of which has been obliterated by the suffix); He will set before the eyes of the sinner, who practically and also in theory denies the divine holiness, the real state of his heart and life, so that he shall be terrified at it. Instead of הָיֹה, the infin. intensit. here, under the influence of the close connection of the clauses (Ew. §240, c), is הֱיֹות; the oratio obliqua begins with it, without כִּי (quod). כָמֹוךָ exactly corresponds to the German deines Gleichen, thine equal.

Isa 17:10  Because thou hast forgotten the God of thy salvation, and hast not been mindful of the rock of thy strength, therefore shalt thou plant pleasant plants, and shalt set it with strange slips: 

Strange slips?  Gill:  and shall set it with strange slips; with foreign ones, such as are brought from other countries, and are scarce and dear, and highly valued; and by "plants" and "slips" may be meant false and foreign doctrines, inculcating idolatry and superstition, which are pleasing to the flesh (u). 

JFB:  strange slips — cuttings of plants from far, and therefore valuable.

Isa 17:12  Woe to the multitude of many people, which make a noise like the noise of the seas; and to the rushing of nations, that make a rushing like the rushing of mighty waters! 

Isa 17:13  The nations shall rush like the rushing of many waters: but God shall rebuke them, and they shall flee far off, and shall be chased as the chaff of the mountains before the wind, and like a rolling thing before the whirlwind.

rushing - H7588 - From H7582; uproar (as of rushing); by implication destruction.

• H7582 - A primitive root; to rush; by implication to desolate.

He brought me up also out of an horrible pit, out of the miry clay, and set my feet upon a rock, and established my goings.  (Psalm 40:2)

Which stilleth the noise of the seas, the noise of their waves, and the tumult of the people.  (Psalm 65:7)

Forget not the voice of thine enemies: the tumult of those that rise up against thee increaseth continually.  (Psalm 74:23)

Therefore hell hath enlarged herself, and opened her mouth without measure: and their glory, and their multitude, and their pomp, and he that rejoiceth, shall descend into it. (Isaiah 5:14)

The noise of a multitude in the mountains, like as of a great people; a tumultuous noise of the kingdoms of nations gathered together: the LORD of hosts mustereth the host of the battle.  (Isaiah 13:4)

A noise shall come even to the ends of the earth; for the LORD hath a controversy with the nations, he will plead with all flesh; he will give them that are wicked to the sword, saith the LORD.  (Jeremiah 25:31)
