我查了一下圣经，创4：1里的“同房”，KJV译作knew。其原文Strong's Number 03045 希伯来语yada，其意思，嘿嘿，就是知道、认识、了解
1) to know
a) (Qal)
1) to know
a) to know, learn to know
b) to perceive
c) to perceive and see, find out and discern
d) to discriminate, distinguish
e) to know by experience
f) to recognise, admit, acknowledge, confess
g) to consider

2) to know, be acquainted with

3) to know (a person carnally)

4) to know how, be skilful in

5) to have knowledge, be wise
b) (Niphal)

1) to be made known, be or become known, be revealed

2) to make oneself known

3) to be perceived

4) to be instructed

c) (Piel) to cause to know

d) (Poal) to cause to know

e) (Pual)

1) to be known

2) known, one known, acquaintance (participle)

f) (Hiphil) to make known, declare

g) (Hophal) to be made known

h) (Hithpael) to make oneself known, reveal oneself

在旧约里用了947次，KJV的翻译know 645, known 105, knowledge 19, perceive 18, shew 17, tell 8, wist 7, understand 7, certainly 7, acknowledge 6, acquaintance 6, consider 6, declare 6, teach 5, misc 85;

我可没有精力翻中文圣经对照，（如果哪位从彩虹退到旷野的，做了中文的commentary，请让我知道，咳咳，不是同房的同义词呕）。不过这么多用法中，除了翻译成“同房”外，许多是简单的知道的意思，比如

创3:5 因为　神“知道”、你们吃的日子眼睛就明亮了、你们便如　神能“知道”善恶。
创4:9 耶和华对该隐说、你兄弟亚伯在哪里．他说、我不“知道”、我岂是看守我兄弟的吗。

关于人和神之间的关系，有例如
Psm 36:10 愿你常施慈爱给认识你的人．常以公义待心里正直的人．
Psm 46:10 你们要休息、要知道我是　神．我必在外邦中被尊崇、在遍地上也被尊崇。
Psm 144:3 耶和华阿、人算甚么、你竟认识他．世人算甚么、你竟顾念他

看来这个词，有相当广泛的意思。除了表达亲密关系的同房，也有非常泛泛的了解。所以人和神的认识，真的能和夫妻的同房相对应吗？我现在开始怀疑了。请搞神学的筒子们出来解解希伯来文，语法什么的。
