The _internal_ evidence for the genuineness of these chapters has already been partly considered in an incidental way. It is found in the purity of the Hebrew, which belongs to the age of Isaiah, not of Cyrus; in the undeniable allusions to the temple sacrifices and oblations as then existing (43:23, 24), and to the sin of seeking heathen alliances (57:9); and especially in the fact that a writer living near the close of the exile must have referred in a more particular and historic way to the great events connected with Cyrus' conquests. It may be added that there are in the later prophets some clear allusions to this part of Isaiah. Jeremiah, who undeniably made use of prophecies contained in the first part of Isaiah, was acquainted with the second part also. Compare Jer. 10:3,4, with Isa. 40:19, 20; 41:7; Jer. 31:35, with Isa. 51:15, where a whole clause is repeated from Isaiah, which agrees in the Hebrew to every letter; Jer. 50:2, with Isa. 46:1, 2. Compare also Zeph. 2:15, with Isa. 47:8; Nah. 1:15, with Isa. 52:7. 9. The arguments urged against the genuineness of certain sections of the first part of Isaiah are for substance the same as these that have now been examined, and need not a separate consideration. We come on solid grounds to the conclusion that Isaiah was the author of the whole collection of prophecies which bear his name, and that the arrangement of these prophecies in their present form also proceeded from him.
