He lodgeth - He remains as a guest at his house. See Acts 9:43.

By the sea-side - Joppa was a seaport on the Mediterranean. Tanneries are erected on the margin of streams or of any body of water to convey away the filth produced in the operation of dressing skins.

Simon a tanner - See the note on Acts 9:43.

What thou oughtest to do - From this it appears that matters of great moment had occupied the mind of Cornelius. He was not satisfied with the state of his own soul, nor with the degree he possessed of religious knowledge; and he set apart a particular time for extraordinary fasting and prayer, that God might farther reveal to him the knowledge of his will. Perhaps he had heard of Jesus, and had been perplexed with the different opinions that prevailed concerning him, and now prayed to God that he might know what part he should take; and the answer to this prayer is, "Send to Joppa for Simon Peter, he shall tell thee what thou oughtest to do." This clause, so explanatory, is wanting in almost every MS. and version of note. Griesbach and some others have left it out of the text. But see Acts 11:14, where it stands in substance.

He lodgeth with one Simon a tanner, &c. Simon the tanner was his host; this man very probably was a good man, and one that lodged strangers; of his trade; see Gill on Acts 9:43.

whose house is by the sea side; Joppa was a sea port, 2 Chronicles 2:16 Jonah 1:3 hence we read of , "the sea of Joppa" (x); and also of , "the port of Joppa" (y); now Simon's house was in the outer part of the city, and by the sea side, as well for convenience for his business, as because such trades might not be exercised within a city; being nauseous and disagreeable, because of their skins and manner of dressing them, and the dead carcasses from whence they often took them off; hence that rule of the Jews (z),

"they place dead carcasses, graves, , "and a tanner's workshop", (in which he dresses his skins,) fifty cubits from the city; nor do they make a tanner's workshop, but at the eastern part of the city. R. Abika says, it may be made at every part excepting the west.''

The reason of that, as given by the (a) commentators, is, because prayer was made towards the west, where the temple stood, and the divine presence was. The Ethiopic version very wrongly renders it, "and the house of Cornelius is near the sea"; for not his, but Simon's is meant:

he shall tell thee what thou oughtest to do; he was to tell him words, or to deliver doctrines to him, by which he and his family would be better instructed in the way of salvation, and arrive to a greater degree of knowledge of Christ, and faith in him, and be brought to a submission to his commands and ordinances; see Acts 10:22, this clause is left out in the Alexandrian copy, and in some others, and in the Syriac and Arabic versions.

A tanner

Showing that the strictness of the Jewish law was losing its hold on Peter; since the tanner's occupation was regarded as unclean by strict Jews, and the tanners were commanded to dwell apart. "If a tanner married without mentioning his trade, his wife was permitted to get a divorce. The law of levirate marriage might be set aside if the brother-in-law of the childless widow was a tanner. A tanner's yard must be at least fifty cubits from any town" (Farrar, "Life and Work of St. Paul").

By the seaside

Outside the walls, both for proximity to the business, and because of the ceremonial requirement referred to above. Mr. William C. Prime, describing a visit to Joppa, says: "I was walking along the sea-beach, looking for shells, and at about a fourth of a mile from the city, to the southward, I found two tanneries directly on the seaside. I observed that the rocks in front of them were covered with the water a few inches deep, and that they soaked their hides on these rocks, and also submitted them to some process in the water which I did not stop to understand" ("Tent-life in the Holy Land").

Of them that waited on him continually (προσκαρτερούν των αὐτῷ)

See on Acts 1:14.

He lodgeth with one Simon a tanner, whose house is by the sea side: he shall tell thee what thou oughtest to do.

10:6 Simon a tanner, whose house is by the sea side. See PNT Ac 9:43. Tanners were required, by the ancient sanitary laws, to live outside city walls, and had to be near plenty of water (Hackett).

Tell thee what thou oughtest to do. As the angel says that his prayer was heard, he had surely prayed that he might know what to do.

10:1-8 Hitherto none had been baptized into the Christian church but Jews, Samaritans, and those converts who had been circumcised and observed the ceremonial law; but now the Gentiles were to be called to partake all the privileges of God's people, without first becoming Jews. Pure and undefiled religion is sometimes found where we least expect it. Wherever the fear of God rules in the heart, it will appear both in works of charity and of piety, neither will excuse from the other. Doubtless Cornelius had true faith in God's word, as far as he understood it, though not as yet clear faith in Christ. This was the work of the Spirit of God, through the mediation of Jesus, even before Cornelius knew him, as is the case with us all when we, who before were dead in sin, are made alive. Through Christ also his prayers and alms were accepted, which otherwise would have been rejected. Without dispute or delay Cornelius was obedient to the heavenly vision. In the affairs of our souls, let us not lose time.
