For this is what the Lord has told me: “I will wait and watch from my place, like scorching heat produced by the sunlight, like a cloud of mist in the heat of harvest.” — Isa 18:4 NET
Assyria marched against Ethiopia. And as the armies advance, God makes no effort to arrest them; it seems as though they will be allowed to work their will. He is still watching them from His dwelling place, the sun still shines on them; but before the harvest, the whole of the proud army of Assyria is smitten as easily as when sprigs are cut off by the pruning hook of the husbandman.
Is not this a marvelous conception of God—being still and watching? His stillness is not acquiescence. His silence is not consent. He is only biding His time, and will arise, in the most opportune moment, and when the designs of the wicked seem on the point of success, to overwhelm them with disaster. As we look out on the evil of the world; as we think of the apparent success of wrong-doing; as we wince beneath the oppression of those that hate us, let us remember these marvelous words about God being still and beholding.
There is another side to this. Jesus beheld His disciples toiling at the oars through the stormy night; and watched though unseen, the successive steps of the anguish of Bethany, when Lazarus slowly passed through the stages of mortal sickness, until he succumbed and was borne to the rocky tomb. But He was only waiting the moment when He could interpose most effectually. Is He still to thee? He is not unobservant; He is beholding all things; He has His finger on thy pulse, keenly sensitive to all its fluctuations. He will come to save thee when the precise moment has arrived.

And therefore will the LORD wait, that he may be gracious unto you, and therefore will he be exalted, that he may have mercy upon you: for the LORD is a God of justice: blessed are all they that wait for him. — Isa. 30:18
And it shall be said in that day, Behold, this is our God; we have waited for him, and he will save us: this is the LORD; we have waited for him, we will be glad and rejoice in his salvation. — Isa. 25:9
He does not delight in the strength of the horse;
He takes no pleasure in the legs of a man.
The LORD takes pleasure in those who fear Him,
In those who hope in His mercy. — Psalm 147:10-11
They who wait for the Lord shall renew their strength;
they shall mount up with wings like eagles;
they shall run and not be weary;
they shall walk and not faint. — Isa. 40:31
