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.
Berean Study Bible (BSB) - Isaiah 27:9 >Therefore Jacob’s guilt will be atoned for, and the full fruit of the removal of his sin will be this: When he makes all the altar stones like crushed bits of chalk, no Asherah poles or incense altars will remain standing.
