Read Isaiah 27:9 Using Other Translations
By this therefore shall the iniquity of Jacob be purged; and this is all the fruit to take away his sin; when he maketh all the stones of the altar as chalkstones that are beaten in sunder, the groves and images shall not stand up.
Therefore by this the guilt of Jacob will be atoned for, and this will be the full fruit of the removal of his sin: when he makes all the stones of the altars like chalkstones crushed to pieces, no Asherim or incense altars will remain standing.
The LORD did this to purge Israel’s wickedness, to take away all her sin. As a result, all the pagan altars will be crushed to dust. No Asherah pole or pagan shrine will be left standing.
