Frog

Boyd’s Bible Dictionary:

The Egyptian species akin to our own
Source of one of the plagues (Ex. 8:2-142And if thou refuse to let them go, behold, I will smite all thy borders with frogs: 3And the river shall bring forth frogs abundantly, which shall go up and come into thine house, and into thy bedchamber, and upon thy bed, and into the house of thy servants, and upon thy people, and into thine ovens, and into thy kneadingtroughs: 4And the frogs shall come up both on thee, and upon thy people, and upon all thy servants. 5And the Lord spake unto Moses, Say unto Aaron, Stretch forth thine hand with thy rod over the streams, over the rivers, and over the ponds, and cause frogs to come up upon the land of Egypt. 6And Aaron stretched out his hand over the waters of Egypt; and the frogs came up, and covered the land of Egypt. 7And the magicians did so with their enchantments, and brought up frogs upon the land of Egypt. 8Then Pharaoh called for Moses and Aaron, and said, Entreat the Lord, that he may take away the frogs from me, and from my people; and I will let the people go, that they may do sacrifice unto the Lord. 9And Moses said unto Pharaoh, Glory over me: when shall I entreat for thee, and for thy servants, and for thy people, to destroy the frogs from thee and thy houses, that they may remain in the river only? 10And he said, To morrow. And he said, Be it according to thy word: that thou mayest know that there is none like unto the Lord our God. 11And the frogs shall depart from thee, and from thy houses, and from thy servants, and from thy people; they shall remain in the river only. 12And Moses and Aaron went out from Pharaoh: and Moses cried unto the Lord because of the frogs which he had brought against Pharaoh. 13And the Lord did according to the word of Moses; and the frogs died out of the houses, out of the villages, and out of the fields. 14And they gathered them together upon heaps: and the land stank. (Exodus 8:2‑14)). Elsewhere only in Psalm 78:45; 105:3045He sent divers sorts of flies among them, which devoured them; and frogs, which destroyed them. (Psalm 78:45)
30Their land brought forth frogs in abundance, in the chambers of their kings. (Psalm 105:30)
; Revelation 16:1313And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet. (Revelation 16:13).

Concise Bible Dictionary:

This well-known reptile is very numerous in Palestine. It is only referred to in the O. T. in connection with the second of the plagues in Egypt (Ex. 8:2-142And if thou refuse to let them go, behold, I will smite all thy borders with frogs: 3And the river shall bring forth frogs abundantly, which shall go up and come into thine house, and into thy bedchamber, and upon thy bed, and into the house of thy servants, and upon thy people, and into thine ovens, and into thy kneadingtroughs: 4And the frogs shall come up both on thee, and upon thy people, and upon all thy servants. 5And the Lord spake unto Moses, Say unto Aaron, Stretch forth thine hand with thy rod over the streams, over the rivers, and over the ponds, and cause frogs to come up upon the land of Egypt. 6And Aaron stretched out his hand over the waters of Egypt; and the frogs came up, and covered the land of Egypt. 7And the magicians did so with their enchantments, and brought up frogs upon the land of Egypt. 8Then Pharaoh called for Moses and Aaron, and said, Entreat the Lord, that he may take away the frogs from me, and from my people; and I will let the people go, that they may do sacrifice unto the Lord. 9And Moses said unto Pharaoh, Glory over me: when shall I entreat for thee, and for thy servants, and for thy people, to destroy the frogs from thee and thy houses, that they may remain in the river only? 10And he said, To morrow. And he said, Be it according to thy word: that thou mayest know that there is none like unto the Lord our God. 11And the frogs shall depart from thee, and from thy houses, and from thy servants, and from thy people; they shall remain in the river only. 12And Moses and Aaron went out from Pharaoh: and Moses cried unto the Lord because of the frogs which he had brought against Pharaoh. 13And the Lord did according to the word of Moses; and the frogs died out of the houses, out of the villages, and out of the fields. 14And they gathered them together upon heaps: and the land stank. (Exodus 8:2‑14); Psa. 78:4545He sent divers sorts of flies among them, which devoured them; and frogs, which destroyed them. (Psalm 78:45); Psa. 105:3030Their land brought forth frogs in abundance, in the chambers of their kings. (Psalm 105:30)). In the N. T. three unclean spirits like frogs come out of the mouths of the dragon, the beast, and the false prophet (Rev. 16:1313And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet. (Revelation 16:13)). Frogs are remarkable for groveling in the mire, with great noise and activity in the night.
