Please read the passage before reading the commentary
One most sacred responsibilities of God’s people was that they welcome the stranger and traveler. Travelers were at great risk in towns as well as on the roads. Hospitality offered the vulnerable traveler protection from weather and safety from the riffraff of town. Sodom and Gomorrah were condemned for not welcoming and protecting Lot, his family, and the special messengers from God. This duty of hospitality was considered of greater importance than temple worship.
Apparently, from the content of this passage, the Israelites were faithful temple-goers, but very lapse on hospitality. The offerings of animals, wheat and the other elements of sacrifices, the prophet declared were unwanted by the Lord. Like the difference between ham and eggs, one being a donation and the other a commitment, sacrificing in the temple was a donation, but caring the needs of hospitality was a commitment. The one required something outside of the person and the other demanded the time and energy from within the person. Our time spent in worship of God in temple or church means nothing if we do not see God in the people who need our help. In temple or church, we see God veiled in mystery; in people we see God veiled in people.
The resolution Isaiah offered was to make justice our aim, to redress the wronged, to care for the orphan and the widow. The prophets has the same command for us, to make justice our aim, not laws but justice, which is to provide for the needy in our society.
As our country prepares for the election of a President and new Congress, we should do well to compare the promises and the platforms of candidates to find the candidates and parties that follow best the statements of the prophet.
