II. Necessary instructions given them how to repent. 1. They must bethink themselves what to say to God when they come to him: Take with you words. They are required to bring, not sacrifices and offerings, but penitential prayers and supplications, the fruit of thy lips, yet not of the lips only, but of the heart, else words are but wind. One of the rabbin says, They must be such words as proceed from what is spoken first in the inner man; the heart must dictate to the tongue. We must take good words with us, by taking good thoughts and good affections with us. Verbaque prævisam rem non invita sequentur—Those who master a subject are seldom at a loss for language. Note, When we come to God we should consider what we have to say to him; for, if we come without an errand, we are likely to go without an answer. Ezra ix. 10, What shall we say? We must take with us words from the scripture, take them from the Spirit of grace and supplication, who teaches us to cry, Abba, Father, and makes intercession in us. 2. They must bethink themselves what to do. They must not only take with them words, but must turn to the Lord; inwardly in their hearts, outwardly in their lives.
