1 Samuel 12:14

“If ye will fear the Lord, and serve him, and obey his voice, etc.] All worship and service of God, and obedience to his word and ordinances, should spring from fear and reverence of him; and therefore the whole of worship, both external and internal, is sometimes expressed by the fear of the Lord: and not rebel against the commandment of the Lord; break it, and thereby exasperate him, and provoke him to wrath and bitterness: then shall both ye, and also the king that reigneth over you, continue following the Lord your God; the Targum is, “after the worship of the Lord your God;” which was their duty to do, and is expressed in the preceding clauses; and this therefore is rather a promise of…”

“Then, &c. - Heb. then shall - ye - be, (that is, walk, or go) after the Lord; that is, God shall still go before you, as he hath hitherto done, as your leader or governor, to direct, protect, and deliver you; and he will not forsake you, as you have given him just cause to do. Sometimes this phrase of going after the Lord, signifies a man's obedience to God; but here it is otherwise to be understood, and it notes not a duty to be performed, but a privilege to be received upon the performance of their duty; because it is opposed to a threatening denounced in case of disobedience, in the next verse. 1 Kings (1 Samuel) 12:15”

“12:14-15 To show that even under a monarchy Israel must still keep its covenant with the Lord—who was always to be their true king—Samuel echoed language from the Sinai covenant (e.g., Exod 19:5-6; Lev 26; Deut 30:11-20). 12:14 Worship is meaningless if it does not result in obedience.”

“If ye will: Lev 20:1-13; Deu 28:1-14; Jos 24:14, Jos 24:20; Psa 81:12-15; Isa 3:10; Rom 2:7 commandment: Heb. mouth continue: Heb. be after 1 Kings (1 Samuel) 12:15”
