We see the way in which a poor Israelite might become a slave in the case of the sons of the widow whose oil was multiplied by Elisha. "Thy servant my husband is dead; (and thou knowest that thy servant did fear the Lord:) and the creditor is come to take unto him my two sons to be bondmen" (2 Kings 4:1).
And in the time of Nehemiah, "Some also there were that said, We have mortgaged our lands, vineyards, and houses, that we might buy corn, because of the dearth.… And, lo, we bring into bondage our sons and our daughters to be servants, and some of our daughters are brought unto bondage already: neither is it in our power to redeem them; for other men have our lands and vineyards" (Nehemiah 5:3-5).
But the fact that an Israelite could not be kept in slavery for more than six years (Exodus 21:2), and that the period of his service had to be still shorter if the jubilee fell before the seventh year, and the further fact that at the time of the jubilee he would not only he free, but recover any ancestral property that he had forfeited, so that he might become once more on an equality with his master, would have made his position totally different from the hopeless, helpless state of the Greek or Roman slave, even without the positive command that he was to be treated, not as a bondservant: but as an hired servant, and as a sojourner.
All alike, master and bondsman, were the slaves of God, and therefore not only were they, so far, on an equality one with another, but the master would be encroaching on the right of God if he claimed God's slaves for his own inalienably.
