KJV Isaiah 13 : 9
9 Behold, the day of the LORD cometh, cruel both with wrath and fierce anger, to lay the land desolate: and he shall destroy the sinners thereof out of it.
9 הנה יום יהוה בא אכזרי ועברה וחרון אף לשום הארץ לשמה וחטאיה ישמיד ממנה׃
I find it a little bit baffling that God's day is said to be cruel in the above text.God who is descibed as love,joy,peace in several texts throughout the Bible but here it's said his day is cruel.
How can cruelty be associated with the God of love
How can we understand the above text?
