On @ light; the sun, Genesis:41:45Genesis:41:50), the great seat of sun-worship, called also Bethshemesh Jeremiah:43:13) and Aven Ezekiel:30:17), stood on the east bank of the Nile, a few miles north of Memphis, and near Cairo, in the north-east. The Vulgate and the LXX. Versions have "Heliopolis" ("city of the sun") instead of On in Genesis and of Aven in Ezekiel. The "city of destruction" Isaiah speaks of (19:18, marg. "of Heres;" Heb. 'Ir-ha-heres, which some MSS. read Ir-ha-heres, i.e., "city of the sun") may be the name given to On, the prophecy being that the time will come when that city which was known as the "city of the sun-god" shall become the "city of destruction" of the sun-god, i.e., when idolatry shall cease, and the worship of the true God be established. In ancient times this city was full of obelisks dedicated to the sun. Of these only one now remains standing. "Cleopatra's Needle" was one of those which stood in this city in front of the Temple of Tum, i.e., "the sun." It is now erected on the Thames Embankment, London. "It was at On that Joseph wooed and won the dark-skinned Asenath, the daughter of the high priest of its great temple." This was a noted university town, and here Moses gained his acquaintance with "all the wisdom of the Egyptians."
Onesimus @ useful, a slave who, after robbing his master Philemon (q.v.) at Colosse, fled to Rome, where he was converted by the apostle Paul, who sent him back to his master with the epistle which bears his name. In it he beseeches Philemon to receive his slave as a "faithful and beloved brother." Paul offers to pay to Philemon anything his slave had taken, and to bear the wrong he had done him. He was accompanied on his return by Tychicus, the bearer of the Epistle to the Colossians Philemon:1:16-18). The story of this fugitive Colossian slave is a remarkable evidence of the freedom of access to the prisoner which was granted to all, and "a beautiful illustration both of the character of St. Paul and the transfiguring power and righteous principles of the gospel."
Onesiphorus @ bringing profit, an Ephesian Christian who showed great kindness to Paul at Rome. He served him in many things, and had oft refreshed him. Paul expresses a warm interest in him and his household ( 2Timothy:1:16-182Timothy:4:19).
Onion @ The Israelites in the wilderness longed for the "onions and garlick of Egypt" Numbers:11:5). This was the _betsel_ of the Hebrews, the Allium cepe of botanists, of which it is said that there are some thirty or forty species now growing in Palestine. The onion is "the 'undivided' leek, _unio_, _unus_, one."
Ono @ a town of Benjamin, in the "plain of Ono" ( 1Chronicles:8:12; Ezra:2:33); now Kefr 'Ana, 5 miles north of Lydda, and about 30 miles north-west of Jerusalem. Not succeeding in their attempts to deter Nehemiah from rebuilding the walls of Jerusalem, Sanballat and Tobiah resorted to strategem, and pretending to wish a conference with him, they invited him to meet them at Ono. Four times they made the request, and every time Nehemiah refused to come. Their object was to take him prisoner.
Onycha @ a nail; claw; hoof, (Heb. sheheleth; Exodus:30:34), a Latin word applied to the operculum, i.e., the claw or nail of the strombus or wing-shell, a univalve common in the Red Sea. The opercula of these shell-fish when burned emit a strong odour "like castoreum." This was an ingredient in the sacred incense.
Onyx @ a hail; claw; hoof, (Heb. shoham), a precious stone adorning the breast-plate of the high priest and the shoulders of the ephod Exodus:28:9-12, 20; 35:27; Job:28:16; Ezekiel:28:13). It was found in the land of Havilah Genesis:2:12). The LXX. translates the Hebrew word by smaragdos, an emerald. Some think that the sardonyx is meant. But the onyx differs from the sardonyx in this, that while the latter has two layers (black and white) the former has three (black, white, and red).
