Boyd’s Bible Dictionary:
(dregs). Sediment of liquor. Settled, pure wine (Isa. 25:66And in this mountain shall the Lord of hosts make unto all people a feast of fat things, a feast of wines on the lees, of fat things full of marrow, of wines on the lees well refined. (Isaiah 25:6)); sloth (Jer. 48:1111Moab hath been at ease from his youth, and he hath settled on his lees, and hath not been emptied from vessel to vessel, neither hath he gone into captivity: therefore his taste remained in him, and his scent is not changed. (Jeremiah 48:11)); extreme suffering (Psa. 75:88For in the hand of the Lord there is a cup, and the wine is red; it is full of mixture; and he poureth out of the same: but the dregs thereof, all the wicked of the earth shall wring them out, and drink them. (Psalm 75:8)).
Concise Bible Dictionary:
“Wines on the lees” are wines left undisturbed on their sediment to mature (Isa. 25:66And in this mountain shall the Lord of hosts make unto all people a feast of fat things, a feast of wines on the lees, of fat things full of marrow, of wines on the lees well refined. (Isaiah 25:6)). The expression “settled on the lees” is used figuratively of Moab, which had not been disturbed as other nations (Jer. 48:1111Moab hath been at ease from his youth, and he hath settled on his lees, and hath not been emptied from vessel to vessel, neither hath he gone into captivity: therefore his taste remained in him, and his scent is not changed. (Jeremiah 48:11)). Also for those who in Jerusalem remained in the Jordan valley indifferent and undisturbed amidst the evils upon which punishments were threatened (Zeph. 1:1212And it shall come to pass at that time, that I will search Jerusalem with candles, and punish the men that are settled on their lees: that say in their heart, The Lord will not do good, neither will he do evil. (Zephaniah 1:12)). A very significant type of the poor apathetic world, and of the self-satisfied and unconcerned spirit of Christendom.
