Psalm 94:5-15 and Isaiah 10:5-7, 13b-16

Psalm 94:5-15
5 They have humiliated your people, O Lord, and they have harassed your inheritance.
6 They have executed the widow and the new arrival, and they have slaughtered the orphan.
7 And they have said, "The Lord will not see, nor will the God of Jacob understand."
8 Understand, you senseless ones among the people. And be wise at last, you foolish ones.
9 He who formed the ear, will he not hear? And he who forged the eye, does he not look closely?
10 He who chastises nations, he who teaches man knowledge, will he not rebuke?
11 The Lord knows the thoughts of men: that these are in vain.
12 Blessed is the man whom you will instruct, O Lord. And you will teach him from your law.
13 So may you soothe him from the evil days, until a pit may be dug for sinners.
14 For the Lord will not drive away his people, and he will not abandon his inheritance,
15 even until the time when justice is being converted into judgment, and when those who are close to justice are all those who are upright of heart. 
Isaiah 10:5-7, 13b-16
5 Woe to Assur! He is the rod and the staff of my fury, and my indignation is in their hands.
6 I will send him to a deceitful nation, and I will order him against the people of my fury, so that he may take away the plunder, and tear apart the prey, and place it to be trampled like the mud of the streets.
7 But he will not consider it to be so, and his heart will not suppose it to be this way. Instead, his heart will be set to crush and to exterminate more than a few nations.
and I have plundered their leaders, and, like one with power, I have pulled down those residing on high.
14 And my hand has reached to the strength of the people, as to a nest. And, just as the eggs which have been left behind are gathered, so have I gathered the entire earth. And there was no one who moved a wing, or opened a mouth, or uttered a snarl."
15 Should the axe glorify itself over him who wields it? Or can the saw exalt itself over him who pulls it? How can a rod lift itself up against him who wields it, or a staff exalt itself, though it is only wood?
16 Because of this, the sovereign Lord, the Lord of hosts, will send leanness among his fat ones. And under the influence of his glory, a burning ardor will rage, like a consuming fire.
