Iii. Reconciliation In Judaism
II. THE 
αταλλάσσω WORD-GROUP IN THE SEPTUAGINT
αταλλάσσω is found but once in the canonical Scriptures of the Old Testament, namely Jeremiah 31(48) : 39, where MT reads ’êkh
hattâh, but where the LXX appears to mean, ‘How is it changed!’ The passage does not help us much.The noun αταλλαγή occurs in Isaiah 9: 5 where it is doubtful whether the LXX can be derived from MT. The former seems to mean ‘For they will recompense for every robe obtained by deceit, and (every) garment with compensation (µετὰ αταλλαγῆς)’. Although the passage is difficult it seems clear that αταλλαγή is used in its older sense of something given in exchange, an equivalent or substitute.

The use of the other words in this word-group does not help us greatly, with one exception, namely the use of διαλλάσσω when the Philistine lords say of David, ‘wherewith will this man be reconciled to his master?’ (I Sa. 29 : 4.). The point here is that David is spoken of as being reconciled, although the enmity to be removed is not his, but Saul’s. This has its importance for an understanding of passages wherein man is said to be reconciled to God.
