It depends on the meaning of "knew." The possibly apocryphal Book of Bush, of which only a single fragment of text has survived, relates just what a Bush of the ancient world "knew," and should have known:
1. . . . Verily, did Bush then goeth in unto his helpmeet, Laura, and he lieth there with her, and he knew her.
2. And, lo, Laura did conceive and begat she unto Bush two maidens, Jenna and Barbara, and fair and comely they were, and maketh not the people to groan.
3. And the people were pleased with this issue, and did rejoice, and bloweth they did upon the pipe and plucketh they did upon the string, and falleth they did upon one another, in merriment and wonder.
4. Went then the people unto Bush, and gathereth them about him, and beseecheth him they did, saying:
5. "Bush, goeth thou not unto war, but goeth in unto thy helpmeet, Laura, and lieth there with her, and know her, and maketh her to beget more maidens unto thee, fair and comely, and pass thou thy days in idleness and fornication, as did the one before you! Goeth thou not unto war in the Land of Ur and far Babylon!"
6. But Bush heard the people not, and he went not in unto his helpmeet, Laura, and he lay with her not, neither did he know her, and she begat not unto him more maidens, fair and comely. Heeding not the people, unto war Bush went, he and his chieftains, unto the Land of Ur and far Babylon.
7. Then were the people stirred to anger and great mischief, tearing at their raiment, and raising great tumult, saying:
8. "Bush, if thou go not in unto thy helpmeet, Laura, and if thou lieth there not with her, and know her not, and maketh her not to beget unto thee more maidens, fair and comely; but shall pass thou thy days in war in the Land of Ur and far Babylon, then unto thine words shall we hearken not, neither shall we heed the counsel of thy chieftains
9. Verily we say unto to thee, Bush: if thou doeth not these things we ask of thee, and goest thou then unto war and retireth not, we shall come unto thee and thy chieftains, and put our hands upon thee, and we shall cast thee and them from us, unto the darkness beyond the Beltway, where dwelleth only carrion fowl and the Mingled Peoples!"
10. And hearing thus, Bush waxed wroth and did curse the people and did tear his raiment, crying: " I am the Chief of all of thee! I maketh war where I will, and I goeth in unto whom I will, and I goeth neither to the right hand, nor to the left hand, when I will not!"
11. And the people were sore amazed at Bush and his wrothful speech, and in the eleventh month did they take themselves unto the assembly, and there did they throw their lots upon the ground.
12. And the scribes of the people came them unto the assembly and gathered unto them the lots that were upon the ground, yea, all of them, and counted them they did.
13. And the scribes did read the judgment of the people in the lots they had thrown upon the ground, and the judgment was read to the people, and the people were pleased with the judgment that they had made.
14. And went then the people unto Bush and his chieftains, and put they their hands upon them, and cast them away they did, unto the darkness beyond the Beltway, where dwelleth only carrion fowl and the Mingled Peoples . . . .
