[Cronos]

Perhaps you missed it

brother has shades of meaning because Aramaic and other Semitic languages do not differentiate between a blood brother/sister and a cousin or other

For example

1. MAtt 1:2 "Jacob the father of Judah and his brothers," for step-brothers with the same father but different mothers
2. acts 3:17 "17And now, brethren,"
3. Luke 10:29 "and who is my brother"
4. Matt 5:47
5. Matt 23:8
6. Rev 22:9

So, yes, brothers had a wider meaning then just blood brother. And no, the term "Irdu" is not used biblically.

The NT was written in Greek, ok -- not all, but let's take your argument for the sake of argument. Remember also that the words of Jesus were mostly Aramaic or Hebrew or maybe even GReek -- we've already shown that in SEmitic languages like Aramaic/hebrew there is no differntiating term between a blood brother and a cousin, let's examine the GReek ouch outos estin o tekton o uios Marias adelphos de Iakobou Iose kai Iouda kai Simonos

If the term is that the adelphoi have the same mother then it would be ho adelphos But that is not used. Without the article adelphos is non-specific and non-exclusive and can mean kinsmen, relatives

Psalm 69 O God of Israel, 7Because for Thy sake I have borne reproach; Dishonor has covered my face. 8 I have become estranged from MY BROTHERS, and an alien to my MOTHERS SONS.

Are my mothers sons, My COUSINS?
