The people of Israel had formerly given the kingdom to David as a gift (5:1-3), but now they took that gift from him (v. 13).237David knew that Absalom was popular with the people. Evidently he fled Jerusalem to save his own life and to spare the capital from destruction. Perhaps Absalom planned to destroy David's capital as well as to kill the king and reassert Judean supremacy. Clearly David planned to return to Jerusalem (v. 16). He was fleeing from an attack, not going into exile. The Cherethites and Pelethites were David's bodyguard. The 600 men from Gath (v. 18) were probably mercenary soldiers. These foreigners were loyal to David even when his own son deserted him.
"Ancient kings quite often preferred to employ foreign bodyguards, since they were unlikely to be affected by local political considerations or won over by local political factions."238
David later repaid Ittai, another former resident of Gath, for his loyalty by making him commander of one-third of his army (18:2). David urged Ittai to return to Jerusalem and to remain loyal to him there (v. 19), but Ittai insisted on accompanying the king. Ittai's commitment to David (vv. 19-22) recalls Ruth's commitment to Naomi (Ruth 1:16-17). David crossed the Kidron Valley immediately east of Zion and moved up the Mount of Olives that lay on the other side of the valley. In this he anticipated the movement of his descendant, Jesus Christ, who also crossed the Kidron Valley to pray on Mt. Olivet during His passion (John 18:1).
At this time there were two leading priests in Israel, Zadok (who was also a prophet, v. 27) and Abiathar. Probably Zadok was responsible for worship in Jerusalem where David had built a new structure to house the ark. Abiathar seems to have functioned for many years as David's personal chaplain. Earlier Zadok had been in charge of the Gibeon sanctuary (1 Chron. 16:39-42). God's "habitation"(v. 25) most likely refers to the new tent David had recently completed in Jerusalem (cf. 1 Chron. 15:1).
These facts suggest another reason for Absalom's rebellion and the support he enjoyed. Many of the Israelites probably considered David's projects of building a new tabernacle and bringing the ark into Jerusalem inappropriate since Jerusalem was a formerly Canaanite stronghold. Many other people may have shared Michal's reaction (6:16-20).239
David's complete submission to God's authority over his life is admirable (v. 26). The phrase "the fords of the wilderness"(v. 28) probably refers to the place people forded the Jordan River near the wilderness of Judah (cf. 17:22). David did not believe superstitiously that the presence of the ark would insure his victory (cf. 1 Sam. 4:3).
David trudged up the Mount of Olives attired for mourning (v. 30), praying as he wept (v. 31). On Mt. Olivet David was still only a few hundred yards from the City of David. It rises about 200 feet above the city to its east. Walking barefoot (v. 30) symbolized "the shameful exile on which he is now embarking (cf. Isa 20:2-3; cf. similarly Mic 1:8)."240David's friend (i.e., counselor) Hushai came from a family that evidently lived on Ephraim's southern border between Bethel and Ataroth (Josh. 16:2).241He was probably quite old.
Chapter 15 teaches us a lot about friendship. Absalom is the negative example, and David's supporters as he left Jerusalem are the positive ones. David lost Absalom as a friend because he failed to reach out to him in forgiveness. David won the friendship of many others in Israel because he had a heart for God that expressed itself in loving kindness for people (cf. Matt. 22:37-39). This made people love David, and we see the marks of their friendship in their dealings with David in this chapter. The king's servants modeled true servanthood by offering to do whatever David needed them to do (vv. 15-18). Ittai expressed his friendship by being a companion to David (vv. 19-23). Zadok and Abiathar became informants and made sure their friend had the information he needed to guarantee his welfare (vv. 24-29). Hushai was willing to hazard his own safety to defend David in the presence of his enemies (vv. 30-37). These people proved to be "sheltering trees"242for their friend in his hour of need.
"Meanwhile David showed a commendable attitude very much in contrast to Absalom's arrogance. He was completely willing to submit to God's will (verses 25f.), whatever that might prove to be. Such willingness to surrender leadership at the right time is another hallmark of good leadership."243
