Acts 21:4

And finding disciples, we tarried there seven days: who said to Paul through the Spirit, that he should not go up to Jerusalem.

Paul reached Tyre on the coast of Phenicia after a prosperous voyage from Miletus to Patara on the southwest shore of Asia Minor, where he left his ship and boarded another vessel bound for Phenicia that sailed with favoring winds. He arrived about two weeks before Pentecost with time to spare, so his anxiety about reaching Jerusalem in time came to an end.

At Tyre the ship was unloaded, and while it unloaded Paul and his companions sought out and found the few disciples there and stayed with them seven days. Through the Holy Spirit the disciples were shown something of the dangers awaiting Paul at Jerusalem — perils of affliction, bonds, imprisonment, and sufferings — and they urged him not to continue there. Their plea was not a divine prohibition, for the same Spirit that revealed the coming afflictions, bonds, and imprisonment still urged Paul forward.

Paul refused to let fear of affliction and imprisonment turn him from his purpose and continued toward Jerusalem as a willing captive. He pressed on from a great desire to be in harmony with his brethren, tenderness toward the weak in faith, reverence for the apostles who had been with Christ and for James the Lord's brother, and a purpose to become all things to all men as far as possible without sacrificing principle, which constrained him to deviate from his firm, decided course. Disregarding the warning did not accomplish conciliation but precipitated the crisis and hastened the predicted sufferings, separating Paul from his fellow laborers, depriving the church of one of its strongest pillars, and bringing sorrow to Christian hearts in every land.
