Verse 4. - No leavened bread; properly, no leaven (שְׂאֹר) (cf. Exodus 12:15). Not only was no leavened bread (מַצָּה) or dough (חָמֵץ) to be used by them, leaven itself was not to be in the house (cf. 1 Corinthians 5:7; see Kitto's 'Cyclop. of Bibl. Lit.,' vol. 3. p. 429).

16:1-17 The laws for the three yearly feasts are here repeated; that of the Passover, that of the Pentecost, that of Tabernacles; and the general law concerning the people's attendance. Never should a believer forget his low estate of guilt and misery, his deliverance, and the price it cost the Redeemer; that gratitude and joy in the Lord may be mingled with sorrow for sin, and patience under the tribulations in his way to the kingdom of heaven. They must rejoice in their receivings from God, and in their returns of service and sacrifice to him; our duty must be our delight, as well as our enjoyment. If those who were under the law must rejoice before God, much more we that are under the grace of the gospel; which makes it our duty to rejoice evermore, to rejoice in the Lord always. When we rejoice in God ourselves, we should do what we can to assist others also to rejoice in him, by comforting the mourners, and supplying those who are in want. All who make God their joy, may rejoice in hope, for He is faithful that has promised.And there shall be no leavened bread seen with thee in all thy coasts seven days,.... For before the passover they were to search diligently every room in the house, and every hole and crevice, that none might remain any where; see Exodus 12:15,

neither shall there be anything of the flesh, which thou sacrificedst the first day at even, remain all night until the morning; which may be understood both of the flesh of the passover lamb, as Aben Ezra, according to Exodus 12:10 and of the flesh of flocks and herds, or of the Chagigah; according to Jarchi this Scripture speaks of the Chagigah of the fourteenth, which was not to remain on the first day of the feast (the fifteenth) until the morning of the second day (the sixteenth).
