Psalms 78:47

47. Hail Not uncommon in Egypt, but this, for severity, exceeded any hail tempest ever known. The miracle consisted in the unwonted severity of the storm, (Exodus 9:22-25,) and in its being foretold. Psalms 78:18.

Sycamore Or fig mulberry, or wild fig tree, abounding in Egypt. Its leaves are like the mulberry, and its fruit like the fig, affording large supplies to the poor, and hence cultivated. 1 Chronicles 27:28.

Frost The Hebrew word occurs nowhere else in Scripture, but as it is parallel to “hail” in the preceding member, the obvious climax of the verse would lead us to suppose icy hailstones of great weight, which destroyed animals, and even trees, where the common hailstone destroyed only the vine. See Joshua 10:11; Revelation 16:21. The marginal reading is “great hailstones.”
