In the conclusion of his speech at Miletus, Paul exhorts the Ephesian Elders to follow his example in working and in praying.  Also, the emotional response reminds us of the great affection that these fledgling churches had for Paul and of the affection that we should have for one another.

[Act 20:33-38 NASB] 33 "I have coveted no one's silver or gold or clothes. 34 "You yourselves know that these hands ministered to my [own] needs and to the men who were with me. 35 "In everything I showed you that by working hard in this manner you must help the weak and remember the words of the Lord Jesus, that He Himself said, 'It is more blessed to give than to receive.'" 36 When he had said these things, he knelt down and prayed with them all. 37 And they [began] to weep aloud and embraced Paul, and repeatedly kissed him, 38 grieving especially over the word which he had spoken, that they would not see his face again. And they were accompanying him to the ship.
