I Timothy 1:7

Sample of their "vain talk" (Ti1 1:6). Desiring--They are would-be teachers, not really so. the law--the Jewish law (Tit 1:14; Tit 3:9). The Judaizers here meant seem to be distinct from those impugned in the Epistles to the Galatians and Romans, who made the works of the law necessary to justification in opposition to Gospel grace. The Judaizers here meant corrupted the law with "fables," which they pretended to found on it, subversive of morals as well as of truth. Their error was not in maintaining the obligation of the law, but in abusing it by fabulous and immoral interpretations of, and additions to, it. neither what they say, nor whereof--neither understanding their own assertions, nor the object itself about which they make them. They understand as little about the one as the other [ALFORD].

After the inscription (Ti1 1:1, Ti1 1:2) we have, I. The charge given to Timothy (Ti1 1:3, Ti1 1:4). II. The true end of the law (Ti1 1:5-11), where he shows that it is entirely agreeable to the gospel. III. He mentions his own call to be an apostle, for which he expresses his thankfulness (Ti1 1:12-16) IV. His doxology (Ti1 1:17). V. A renewal of the charge to Timothy (Ti1 1:18). And of Hymenaeus and Alexander (Ti1 1:19, Ti1 1:20).

1:7 Their aspirations to be teachers of the law of Moses were ironic; their handling of the law was deficient in the light of the Good News, and they neither understood nor fulfilled the law (see 1:8-11).
