我查了一下聖經，創4：1里的“同房”，KJV譯作knew。其原文Strong's Number 03045 希伯來語yada，其意思，嘿嘿，就是知道、認識、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

在舊約里用了947次，KJV的翻譯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;

我可沒有精力翻中文聖經對照，（如果哪位從彩虹退到曠野的，做了中文的commentary，請讓我知道，咳咳，不是同房的同義詞嘔）。不過這麼多用法中，除了翻譯成“同房”外，許多是簡單的知道的意思，比如

創3:5 因為　神“知道”、你們吃的日子眼睛就明亮了、你們便如　神能“知道”善惡。
創4:9 耶和華對該隱說、你兄弟亞伯在哪裡．他說、我不“知道”、我豈是看守我兄弟的嗎。

關於人和神之間的關係，有例如
Psm 36:10 願你常施慈愛給認識你的人．常以公義待心裡正直的人．
Psm 46:10 你們要休息、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 耶和華阿、人算甚麼、你竟認識他．世人算甚麼、你竟顧念他

看來這個詞，有相當廣泛的意思。除了表達親密關係的同房，也有非常泛泛的了解。所以人和神的認識，真的能和夫妻的同房相對應嗎？我現在開始懷疑了。請搞神學的筒子們出來解解希伯來文，語法什麼的。
