Psalm 2:4, 5 He who sits in the heavens shall laugh; The Lord shall hold them in derision. Then He shall speak to them in His wrath, and distress them in His deep displeasure.
There are those who plan against the poor, widow and fatherless, and so God tells them clearly how He will deal with them. As we are seeing in our world; the more men put aside God's wisdom and become more corrupt, the more disasters and diseases increase. The increase of oppression of the poor by the rich and powerful is filling the earth with sorrow and God will . speak to the oppressor in His wrath, and distress them in His deep displeasure.

For additional clarity read Psalm 37:7-16:
37:7 Rest in the LORD, and wait patiently for him: fret not thyself because of him who prospereth in his way, because of the man who bringeth wicked devices to pass.
37:8 Cease from anger, and forsake wrath: fret not thyself in any wise to do evil.
37:9 For evildoers shall be cut off: but those that wait upon the LORD, they shall inherit the earth.
37:10 For yet a little while, and the wicked [shall] not [be]: yea, thou shalt diligently consider his place, and it [shall] not [be].
37:11 But the meek shall inherit the earth; and shall delight themselves in the abundance of peace.
37:12 The wicked plotteth against the just, and gnasheth upon him with his teeth.
37:13 The Lord shall laugh at him: for he seeth that his day is coming.
37:14 The wicked have drawn out the sword, and have bent their bow, to cast down the poor and needy, [and] to slay such as be of upright conversation.
37:15 Their sword shall enter into their own heart, and their bows shall be broken.
37:16 A little that a righteous man hath [is] better than the riches of many wicked.

Also for more clarity read Proverbs 1:22-33:
1:22 How long, ye simple ones, will ye love simplicity? and the scorners delight in their scorning, and fools hate knowledge?
1:23 Turn you at my reproof: behold, I will pour out my spirit unto you, I will make known my words unto you.
1:24 Because I have called, and ye refused; I have stretched out my hand, and no man regarded;
1:25 But ye have set at nought all my counsel, and would none of my reproof:
1:26 I also will laugh at your calamity; I will mock when your fear cometh;
1:27 When your fear cometh as desolation, and your destruction cometh as a whirlwind; when distress and anguish cometh upon you.
1:28 Then shall they call upon me, but I will not answer; they shall seek me early, but they shall not find me:
1:29 For that they hated knowledge, and did not choose the fear of the LORD:
1:30 They would none of my counsel: they despised all my reproof.
1:31 Therefore shall they eat of the fruit of their own way, and be filled with their own devices.
1:32 For the turning away of the simple shall slay them, and the prosperity of fools shall destroy them.
1:33 But whoso hearkeneth unto me shall dwell safely, and shall be quiet from fear of evil.
