[i]Joh 21:7 Therefore that disciple whom Jesus loved saith unto Peter, It is the Lord. Now when Simon Peter heard that it was the Lord, he girt his fisher's coat unto him, (for he was naked,) and did cast himself into the sea.[/i]
[b]His fisher’s coat[/b] - His upper or outer garment or tunic, in distinction from the inner garment or tunic which was worn next the skin. In the case of Peter it may have been made of coarse materials such as fishermen commonly wore, or such as Peter usually wore when he was engaged in this employment. Such garments are common with men of this occupation. This outer garment he probably had laid aside.
[b]He was naked[/b] - He was undressed, with nothing on but the undergarment or tunic. The word does not require us to suppose a greater degree of nakedness than this. See the Mar_14:51 note; also 1Sa_19:24 note.
[b]Did cast himself into the sea[/b] - With characteristic ardor, desirous of meeting again his Lord, and showing his affection for him.

[b]he girt his fisher's coat unto him[/b]. The Greek word επενδυτης, here used, is manifestly the אפונדת of the Hebrews; and which, the Jewish writers say (b), was a strait garment, which a man put on next his flesh to dry up the sweat; and a very proper one for Peter, who had been toiling all night, and very fit for him to swim in; and, by what follows, appears to be put on him next his flesh:
[b]for he was naked[/b]; for to suppose him entirely naked, whilst fishing, being only in company with men, and those parts of nature having a covering, which always require one, was not at all indecent and unbecoming:
[b]and did cast himself into the sea[/b]; the Syriac adds, "that he might come to Christ"; and the Persic, "and he came to Christ"; showing his great love and eagerness to be with him; and, as fearless of danger, risks all to be with Christ; his love being such, that many waters could not quench, nor floods drown.

[b]Dress[/b]
1. Materials used. The earliest and simplest an apron of fig-leaves sewed together (Gen. 3:7); then skins of animals (3:21). Elijah’s dress was probably the skin of a sheep (2 Ki. 1:8). The Hebrews were early acquainted with the art of weaving hair into cloth (Ex. 26:7; 35:6), which formed the sackcloth of mourners. This was the material of John the Baptist’s robe (Mt. 3:4). Wool was also woven into garments (Lev. 13:47; Dt. 22:11; Ezek. 34:3; Job 31:20; Pr. 27:26). The Israelites probably learned the art of weaving linen when they were in Egypt (1 Chr. 4:21). Fine linen was used in the vestments of the high priest (Ex. 28:5), as well as by the rich (Gen. 41:42; Pr. 31:22; Lk. 16:19). The use of mixed material, as wool and flax, was forbidden (Lev. 19:19; Dt. 22:11).
2. Colour. The prevailing colour was the natural white of the material used, which was sometimes rendered purer by the fuller’s art (Ps. 104:1, 2; Isa. 63:3; Mk. 9:3). The Hebrews were acquainted with the art of dyeing (Gen. 37:3, 23). Various modes of ornamentation were adopted in the process of weaving (Ex. 28:6; 26:1, 31; 35:25), and by needle-work (Judg. 5:30; Ps. 45:13). Dyed robes were imported from foreign countries, particularly from Phoenicia (Zeph. 1:8). Purple and scarlet robes were the marks of the wealthy (Lk. 16:19; 2 Sam. 1:24).
3. Form. The robes of men and women were not very much different in form from each other.
a. The “coat” (kethoneth), of wool, cotton, or linen, was worn by both sexes. It was a closely-fitting garment, resembling in use and form our shirt (Jn. 19:23). It was kept close to the body by a girdle (Jn. 21:7). A person wearing this “coat” alone was described as naked (1 Sam. 19:24; Isa. 20:2; 2 Ki. 6:30; Jn. 21:7); deprived of it he would be absolutely naked.
b. A linen cloth or wrapper (sadin) of fine linen, used somewhat as a night-shirt (Mk. 14:51). It is mentioned in Judg. 14:12, 13, and rendered there “sheets.”
c. An upper tunic (meil), longer than the “coat” (1 Sam. 2:19; 24:4; 28:14). In 1 Sam. 28:14 it is the mantle in which Samuel was enveloped; in 1 Sam. 24:4 it is the “robe” under which Saul slept. The disciples were forbidden to wear two “coats” (Mt. 10:10; Lk. 9:3).
d. The usual outer garment consisted of a piece of woollen cloth like a Scotch plaid, either wrapped round the body or thrown over the shoulders like a shawl, with the ends hanging down in front, or it might be thrown over the head so as to conceal the face (2 Sam. 15:30; Esther 6:12). It was confined to the waist by a girdle, and the fold formed by the overlapping of the robe served as a pocket (2 Ki. 4:39; Ps. 79:12; Hag. 2:12; Pr. 17:23; 21:14).
4. Female dress. The “coat” was common to both sexes (Song 5:3). But peculiar to females were
1. the “veil” or “wimple,” a kind of shawl (Ruth 3:15; rendered “mantle,” R.V., Isa. 3:22);
2. the “mantle,” also a species of shawl (Isa. 3:22);
3. a “veil,” probably a light summer dress (Gen. 24:65);
4. a “stomacher,” a holiday dress (Isa. 3:24). The outer garment terminated in an ample fringe or border, which concealed the feet (Isa. 47:2; Jer. 13:22).
5. The dress of the Persians is described in Dan. 3:21.
The reference to the art of sewing are few, inasmuch as the garments generally came forth from the loom ready for being worn, and all that was required in the making of clothes devolved on the women of a family (Pr. 31:22; Acts 9:39).
Extravagance in dress is referred to in Jer. 4:30; Ezek. 16:10; Zeph. 1:8 (R.V., “foreign apparel”); 1 Tim. 2:9; 1 Pet. 3:3. Rending the robes was expressive of grief (Gen. 37:29, 34), fear (1 Ki. 21:27), indignation (2 Ki. 5:7), or despair (Judg. 11:35; Esther 4:1).
Shaking the garments, or shaking the dust from off them, was a sign of renunciation (Acts 18:6); wrapping them round the head, of awe (1 Ki. 19:13) or grief (2 Sam. 15:30; casting them off, of excitement (Acts 22:23); laying hold of them, of supplication (1 Sam. 15:27). In the case of travelling, the outer garments were girded up (1 Ki. 18:46). They were thrown aside also when they would impede action (Mk. 10:50; Jn. 13:4; Acts 7:58).
