[Mat 8:9 KJV] 9 For I am a man under authority, having soldiers under me: and I say to this [man], Go, and he goeth; and to another, Come, and he cometh; and to my servant, Do this, and he doeth [it].

[Psa 33:4-9 KJV] 4 For the word of the LORD [is] right; and all his works [are done] in truth. 5 He loveth righteousness and judgment: the earth is full of the goodness of the LORD. 6 By the word of the LORD were the heavens made; and all the host of them by the breath of his mouth. 7 He gathereth the waters of the sea together as an heap: he layeth up the depth in storehouses. 8 Let all the earth fear the LORD: let all the inhabitants of the world stand in awe of him. 9 For he spake, and it was [done]; he commanded, and it stood fast.
