Judges 13:19

So Manoah took a kid with a meat offering, and offered [it] upon a rock unto the LORD: and [the angel] did wondrously; and Manoah and his wife looked on.

Ver. 19. So Manoah took a kid, &c.] Both the sacrifiser and the altar were extraordinary; but they had Christ's warrant for it. Jdg 19:16

And the angel did wondrously.] Probably by bringing fire out of the rock, as before for Gideon, and consuming the sacrifice.

And Manoah and his wife looked on.] For the confirmation of their faith. This was a high favour. All Israel might see Moses go toward the rock of Rephidim. None but the elders might see him strike it: their unbelief made them unworthy of this privilege. It is no small favour of God to make us witnesses of his wondrous works.
