as. just as. The Lord was dead, therefore Jonah must have been. Nothing is said about his being "preserved alive". That "sign" would have had no relation to what is here signified. See notes on Jonah.
three nights. Apart from these words, "three days" might mean any portion of. day. But "three nights" forbids this interpretation. See App-144 and App-156. Quoted from Jonah 1:17.
the whale's. Greek. ketos. Occ only here. There is nothing about "a whale" either in the Hebrew of Jonah (Matthew 1:17) or in the Greek here. The "great fish" was specially "prepared" by its Creator. See Jonah 1:17.
the heart of the earth. in the earth: i.e. the sepulchre, or tomb, Matthew 27:60; Mark 15:46; Luke 23:53. Joh 19:40. Acts 13:29. It is the Figure of speech Pleonasm (a Hebraism), App-6,. the midst, or "in". See Exodus 15:8; Psalms 46:2; 2 Samuel 18:14.Deuteronomy 4:11.

We are to conclude that the Lord establishes "the literal validity of the history of Jonah", inasmuch as He spoke "not His own words but only words of the Father" (see John 7:16; John 8:28; John 8:46; John 8:47; John 12:49; John 14:10; John 14:24; John 17:8); so that the assertions of modern critics are perilously near blasphemy against God Himself
