We beg (1189) (deomai from deo = to bind) means to ask for something with the sense of pleading, beseeching or begging. To request, to ask for with a sense of urgency and a presumed need. When used in the context of prayer deomai means to make petition, to plead, to ask in prayer, to implore (pray for earnestly) and emphasizes the existence of a need. Deomai is a strong way to ask for something - a leper imploring Jesus to heal him (Lk 5:12), a father's desperate plea to Jesus to cast a demon out of his son (Lk 9:38). To beg in English means to ask for earnestly, urgently or insistently. It implies more urgency than simply asking. The related word deesis, means prayer for a particular need (supplication). The aorist imperative pictures this as an urgent command calling for immediate response! Paul is begging unbelievers because they are but a single heart beat away from an eternal separation from God if they refuse God's gracious offer of reconciliation. Murray comments on the passive voice... While it is possible that this passive is permissive, “let yourselves be reconciled (to God),” it is more probably a true passive, “be reconciled,” or, to bring out the ingressive sense of this aorist, “get reconciled,” with God as the implied agent. Proseuchomai, to pray, is always used of requests addressed to God, whereas deomai, when used in the context of prayer, may be used of requests addressed to man as well. Proseuchomai carries with it a notion of worship which is not present in the word deomai. Deomai emphasizes the intensity of the request. Paul uses deomai to express the heart's desire of the saints at Corinth regarding financial giving, for they were begging us with much urging for the favor of participation in the support of the saints (2Corinthians 8:4) NIDNTT... In the NT deomai occurs only with the meaning to ask request, beseech, beg. 1. It is used in a general sense as a courtesy formula, without any particular object or object clause (cf. the English phrase “I beg you”), followed by direct speech (Acts 8:24; 21:39) or by an infinitive (Acts 26:3). 2. In some passages deomai is used in its full sense of making earnest entreaty, even imploring. There is a warmth, an attractiveness, a winsomeness about it, as in 2Co 5:20 (cf. Acts 2:40); 8:4; 10:2; Gal. 4:12. 3. In all other cases deomai has the religious sense of beseeching Jesus or God. The requests made are quite specific, arising out of real need and expecting definite help of an external or a spiritual nature. Help in a situation of external need is sought from Jesus in Lk 5:12; 9:38. (Brown, Colin, Editor. New International Dictionary of NT Theology. 1986. Zondervan or Computer version) TDNT... The original meaning of déomai is “to lack,” “to need,” and of déÄ"sis, “lack.” But there are few traces of this in the LXX and none in the NT. Richards.... This verb (deomai) and its cognate noun, deesis, emphasize the existence of a need. The individual speaking is deeply aware of a personal need, and out of the need comes a cry for specific help. The cry for help may be addressed to Jesus or to the Father and is often uttered in intercession for others Deomai - 22x in 22v - Matt 9:38; Luke 5:12; 8:28, 38; 9:38, 40; 10:2; 21:36; 22:32; Acts 4:31; 8:22, 24, 34; 10:2; 21:39; 26:3; Ro 1:10; 2 Cor 5:20; 8:4; 10:2; Gal 4:12; 1Th 3:10 NAS = ask(1), beg(6), begged(1), begging(2), beseech(2), implored(1), making request(1), please(1), pray(2), prayed(3), praying(2).

In all uses of the verb of reconciliation in 2 Corinthians 5 (2Cor 5:18, 19, 20) the object or goal of the action is God. As Furnish states reconciliation is not ["only"] of God but from and to God. On behalf of - The preposition huper means in behalf of or for the sake of. The idea is that an ambassador works both “on behalf of Christ” and “in the place of Christ.” For His sake. In His stead. In the place of Christ. Acting on Christ’s behalf and in His place. In essence we are now to be doing what Christ did when He was on earth. Murray Harris adds that... Not only in the words he spoke but also in his whole life Paul was acting in Christ’s name and place. His status was not dependent on the Corinthians to whom he had been sent but on Christ who had sent him (cf. 2Co 1:1). This intimate link between agent and principal is encapsulated in the aphorism of Rabbinic Judaism, “the one who is sent is as the one who sent him,” “a man’s agent is as the man himself.” (International Greek Testament) (Logos)
