God is clear. He calls those who thirst and who are poor to come to Him. He asks rhetorically why those who are poor should spend what little they may have for things that do not satisfy? He says, “Come to Me.” And, He tells every one of us we need not pay. The covenant He “smites” us with is free!
“1 All that thirst, come ye to waters [All ye thirsting, cometh to waters], and ye that have not silver, haste, buy ye, and eat ye; come ye, buy ye, without silver and without any (ex)changing, wine and milk. (All ye who thirst, come to the waters, and ye who have no silver, hasten, buy ye, and eat ye; come ye, and buy ye, wine and milk, without any silver, yea, without any exchanging of money.)
2 Why weigh ye (out) silver, and not in loaves, and your travail, not in fullness? (Why spend ye your silver, but not for loaves, and the fruits of your labour, but ye be not fulfilled?) Ye hearing hear me, and eat ye (that which is) good, and your soul shall delight in fatness.
3 Bow ye [in] your ear, and come ye to me; hear ye, and your soul shall live; and I shall smite with you a covenant everlasting (and I shall strike with you an everlasting covenant), the faithful mercies of David.”
