Isaiah 50:3

I clothe the heavens with blackness, and I make sackcloth their covering.

Ver. 3. I clothe the heavens with blackness.] I did so in that three days' darkness in Egypt, Exo 10:21-22 and shall do so again at the time of my passion. I can therefore, doubtless, deliver you, not only from Babylon, but from sin, death, and hell, by giving you an entrance into heaven by the waters of baptism, and by bringing you out of darkness into my marvellous light. 1Pe 2:9

And make sackcloth their covering.] Ita ut coelum pullata veste obtensum fuisse dixeris. So Revelation 6:12 .
