וַיֹּ֣אמֶר שְׁמוּאֵ֗ל אֶל־כָּל־בֵּ֣ית יִשְׂרָאֵל֮ לֵאמֹר֒ אִם־בְּכָל־לְבַבְכֶ֗ם אַתֶּ֤ם שָׁבִים֙ אֶל־יְהוָ֔ה הָסִ֜ירוּ אֶת־אֱלֹהֵ֧י הַנֵּכָ֛ר מִתּוֹכְכֶ֖ם וְהָעַשְׁתָּר֑וֹת וְהָכִ֨ינוּ לְבַבְכֶ֤ם אֶל־יְהוָה֙ וְעִבְדֻ֣הוּ לְבַדּ֔וֹ וְיַצֵּ֥ל אֶתְכֶ֖ם מִיַּ֥ד פְּלִשְׁתִּֽים׃
撒母耳對以色列全家說：«你們若是全心回歸永恆者，就要把外邦的神明和亞斯她錄從你們中間除掉，立定你們的心歸向永恆者，單單事奉祂，祂就必救你們脫離非利士人的手。»
Sefer HaYashar
Now that it has been explained that the pillars of love are three and we have explained each of them briefly, we can now say that the foundation of the book and its intent is a service in which man can reach the level of fulfilling God’s will till he purifies his heart from its wickedness and cleanses it from its uncleanliness. Then his heart will cleave to the service of God. It is like a garment which you wish to dye. If it is soiled, then the dye will not be fast until you first wash it well and remove all of its stains; then the dye will be fast. Concerning this, Isaiah, the prophet, peace be upon him, said (Isaiah 55:7), “Let the wicked forsake his way, and the man of iniquity his thoughts; and let him return unto the Lord, and He will have compassion upon him, and let him return to our God, for He will abundantly pardon.” And Samuel the prophet said (1 Samuel 7:3), “If ye do return unto the Lord with all your heart, then put away the foreign gods from among you.”
