REFERENCE NEVER ENOUGH
Proverbs 30:15-16 [30:15] The horseleach hath two daughters, crying, Give, give. There are three things that are never satisfied, yea, four things say not, It is enough: [30:16] The grave; and the barren womb ; the earth that is not filled with water; and the fire that saith not, It is enough.
Isaiah 56:11 Yea, they are greedy dogs which can never have enough, and they are shepherds that cannot understand: they all look to their own way, every one for his gain, from his quarter.
Hosea 4:10 For they shall eat, and not have enough: they shall commit whoredom, and shall not increase: because they have left off to take heed to the LORD. (The inhabitants of the land in which Hosea lived)
Haggai 1:6 Ye have sown much, and bring in little; ye eat, but ye have not enough; ye drink, but ye are not filled with drink; ye clothe you, but there is none warm; and he that earneth wages earneth wages to put it into a bag with holes. (Haggai is speaking to the restored remnant of Israel after the Babylonian captivity.)
