Midrash exegesis was largely in the nature of homiletics, expounding the Bible not in order to investigate its actual meaning and to understand the documents of the past but to find religious , moral instruction, and sustenance for the thoughts and feelings of the present. The contrast between explanation of the literal sense and the Midrash, that did not follow the words, was recognized by the Tannaim and the Amoraim, although their idea of the literal meaning of a biblical passage may not be allowed by more modern standards. The above-mentioned tanna, Ishmael b. Elisha said, rejecting an exposition of Eliezer b. Hyrcanus: "Truly, you say to Scripture, 'Be silent while I am expounding!'" (Sifra on Lev. xiii. 49).
