Saw this right to left order in Emacs 23:

בִּּרֵאשׁיתבָּרָּאא לֹהִים אלתשָּׁמַיִם וְ אלת הָ ּאָרֶ ׃

Copy-pasted here in Tbird:


׃ ֶרָאּ ָה תלא ְו םִיַמָּׁשתלא םיִהֹל אאָּרָּבתיׁשאֵרִּּב

First line C-c C-v (CUA) here in Tbird:

בִּּרֵאשׁיתבָּרָּאא לֹהִים אלתשָּׁמַיִם וְ אלת הָ ּאָרֶ ׃

And it doesn't matter which direction the Hebrew text is selected in. In 
fact S-arrow won't move over the Hebrew, character-by-character but it 
selects the whole line, whether characters are in forward or reverse 
order and whether cursor starts at left or right.
