The Israelites were to observe the year of jubilee (lit. blowing the ram's horn) every fiftieth year, the year following seven seven-year periods.285On the Day of Atonement of that year a priest was to blow the ram's horn (shophar) to announce the beginning of the jubilee year. The use of the ram's horn was significant. With this horn God announced His descent on Mt. Sinai, called Israel to be His people, received them into His covenant, united them to Himself, and began to bless them (Exod. 19:13, 16, 19; 20:18).
The year began on the Day of Atonement ". . . to show that it was only with the full forgiveness of sins that the blessed liberty of the children of God could possibly commence."286
No sowing or reaping was to take place, as during the sabbatical years (v. 11). God promised to provide for His people as they rested in response to His gracious promise (vv. 18-23).
"As Israel is God's servant, so the land is Israel's servant. As Israel must cease from her daily work and be restored, so the land must cease from its annual work and be restored. Thus there is a horizontal implementation of the vertical covenant relationship; the redemption of Israelites who lost their freedom and property comes in the year of jubilee (Lev. 25:8-12, 28), the fiftieth year."287
"The Year of Jubilee is not mentioned in the Old Testament outside the Pentateuch. There is no direct biblical evidence regarding its observance in Israel's history, but if its practice was normal, there might have been no occasion to mention it. On the other hand, the apparent failure of Israelites to keep the sabbatical years during the monarchial [sic] period (cf. 26:34-35, 43; 2 Chron. 36:20-21) suggests that the Jubilee might also have been violated."288
