Isaiah 28:13

“But the word of the Lord was unto them precept upon precept, &c.] Was despised and derided by them; they took the prophet’s words out of his mouth, and in a scoffing manner repeated them; which, in the Hebrew text, is in a rhyming form, and were sung and drawled out by them, “Tsau lotsau, Tsau lotsau, Kau lakau, Kau lakau”: this is all he can say to us, and we have from him: precept upon precept, line upon line, line upon line; here a little, [and] there a little; or the words may be rendered, “and the word of the Lord was unto them precept upon precept”, &c.; as it had been, so it still was; the same method was continued to be taken with them, and they still treated as children; and it is…”

“But--rather, "Therefore," namely, because "they would not hear" (Isa 28:12). that they might go--the designed result to those who, from a defect of the will, so far from profiting by God's mode of instructing, "precept upon precept," &c., made it into a stumbling-block (Hos 6:5; Hos 8:12; Mat 13:14). go, and fall--image appropriately from "drunkards" (Isa 28:7-8, which they were) who in trying to "go forward fall backward."”

“Here a little - As this method has been used and was altogether necessary for them; so it still is, and for the future shall be. As they were children in understanding, they shall still continue to be such; they shall be ever learning, and never come to the knowledge of the truth. That - This will be the event, or consequence of their sin: they will fall backward, which is the worst, and most dangerous way of falling; and so be broken to pieces. Isaiah 28:15”

“28:13 one line at a time, one line at a time, a little here, and a little there: The Hebrew here is difficult to understand. The words might be intentional nonsense to illustrate the point that the people were so spiritually blind that God’s clearest revelation was nonsense to them (see 6:9-10).”

“precept upon precept: Isa 28:10; Jer 23:36-38; Hos 6:5, Hos 8:12 that: Isa 6:9, Isa 6:10, Isa 8:14, Isa 8:15; Psa 69:22; Mat 13:14, Mat 21:44; Rom 11:9; Co2 2:16; Pe1 2:7, Pe1 2:8; Pe2 3:16 Isaiah 28:14”
