<p>20:29 <em>I know</em>- By direct Spirit revelation, the Spirit gift of knowledge; because in 1 Tim. 4:1 Paul writes to Timothy in Ephesus, from where these elders were from, that there had been &quot;express&quot; Spirit revelation that some would 'take heed' to false teaching.</p><p><em>That after my departing- </em>Paul warned the new Israel that after his death (&quot;after my departing&quot;) there would be serious apostasy.&nbsp; This is the spirit of his very last words, in 2 Tim. 4. This is exactly the spirit of Moses' farewell speech throughout the book of Deuteronomy, and throughout his final song (Dt. 32). &quot;After my death ye will utterly corrupt yourselves&quot; (Dt. 31:29). &quot;Take heed unto yourselves&quot; is repeated so many times in Deuteronomy (e.g. Dt. 2:4; 4:9,15,23; 11:16; 12:13,19,30; 24:8; 27:9). Exactly as Moses completely revealed all God's counsel to Israel (Acts 7:33; Dt. 33:3).&nbsp;&nbsp;&nbsp;</p><p><em>Fierce wolves</em>- As noted on :28 <em>Take heed</em>, he likely had Jewish false teachers in view. It was consistently the Jews who are presented throughout Acts as coming and disrupting Paul's missionary work after he had made converts. It was Jewish wolves whom the Lord had in mind when He warned the first disciples to &quot;take heed... of wolves&quot; (Mt. 7:15; 10:16; Lk. 10:3).</p><p><em>Shall enter in among you </em><i>and will not spare the flock</i>- This sounds like a fifth column within the new churches, as if they actually became members and worked from within; those referred to in Gal. 2:4 as false brethren who had been smuggled in, or in Jude 4 as the &quot;certain people who have crept in secretly&quot;.</p>
