An example, 1 Chronicles 21:15:

15 And God sent an angel unto Jerusalem to destroy it. And the angel stretched forth his hand unto Jerusalem to destroy it; and God said to the angel, Stay now thine hand, it is enough; for as he was destroying, the Lord beheld Israel, that he repented him of the evil; therefore the Lo rd stayed the angel that destroyed, as he stood by the threshing floor of Ornan, the Jebusite.

Isaiah 29:

1 Woe to Ariel, to Ariel, the city where David dwelt! add ye year to year; let them kill sacrifices. 2 Yet I will distress Ariel, and there shall be heaviness and sorrow; for thus hath the Lord said unto me, It shall be unto Ariel; 3 That I the Lord will camp against her round about, and will lay siege against her with a mount, and I will raise forts against her . 4 And she shall be brought down, and shall speak out of the ground, and her speech shall be low out of the dust; and her voice sha ll be as of one that hath a familiar spirit, out of the ground, and her speech shall whisper out of the dust. 5 Moreover the multitude of her strangers shall be like small dust, and the multitude of the terrible ones shall be as chaff that passeth away;* * yea, it shall be at an instant suddenly. 6 For they shall be visited of the Lord of hosts with thunder, and with earthquake, and great noise, with storm and tempest, and the flame of devouring fire. 7 And the multitude of all the nations that fight against Ariel, even all that fight against her and her munition, and that distress her, shall be as a dream of a night vision. 8 Yea, it shall be unto them even as unto a hungry man who dreameth, and behold, he eateth, but he awaketh and his soul is empty; or like unto a thirsty man who dreameth, and behold, he drinketh, but he awaketh, and behold, he is faint, and his sou l hath appetite. Yea, even so shall the multitude of all the nations be** that fight against mount Zion.
