I Samuel 12:20

Samuel thereupon announced to them first of all, that the Lord would not forsake His people for His great name's sake, if they would only serve Him with uprightness. In order, however, to give no encouragement to any false trust in the covenant faithfulness of the Lord, after the comforting words, "Fear not," he told them again very decidedly that they had done wrong, but that now they were not to turn away from the Lord, but to serve Him with all their heart, and not go after vain idols. To strengthen this admonition, he repeats the תּסוּרוּ לא in Sa1 12:21, with the explanation, that in turning from the Lord they would fall away to idols, which could not bring them either help or deliverance. To the כּי after תּסוּרוּ the same verb must be supplied from the context: "Do not turn aside (from the Lord), for (ye turn aside) after that which is vain." התּהוּ, the vain, worthless thing, signifies the false gods. This will explain the construction with a plural: "which do not profit and do not save, because they are emptiness" (tohu), i.e., worthless beings (elilim, Lev 19:4; cf. Isa 44:9 and Jer 16:19).

We left the general assembly of the states together, in the close of the foregoing chapter; in this chapter we have Samuel's speech to them, when he resigned the government into the hands of Saul, in which, I. He clears himself from all suspicion or imputation of mismanagement, while the administration was in his hands (Sa1 12:1-5). II. He reminds them of the great things God had done for them and for their fathers (Sa1 12:6-13). III. He sets before them good and evil, the blessing and the curse (Sa1 12:14, Sa1 12:15). IV. He awakens them to regard what he said to them, by calling to God for thunder (Sa1 12:16-19). V. He encourages them with hopes that all should be well (Sa1 12:20-25). This is his farewell sermon to that august assembly and Saul's coronation sermon.
