Exodus 16:13-15

Young's Literal Translation

¹³ And it cometh to pass in the evening, that the quail cometh up, and covereth the camp, and in the morning there hath been the lying of dew round about the camp,

¹⁴ and the lying of the dew goeth up, and lo, on the face of the wilderness a thin, bare thing, thin as hoar-frost on the earth.

¹⁵ And the sons of Israel see, and say one unto another, `What [is] it?' for they have not known what it [is]; and Moses saith unto them, `It [is] the bread which Jehovah hath given to you for food.
