The Feast of Mid-Pentecost which ties together the Feasts of Pascha and Pentecost is perhaps not significant in the life of many Orthodox in America, just a minor afterthought in the Post-Paschal season. I found its Old Testament readings to be very meaningful and so reproduce portions of two of the readings here. The readings are both “compilations,” meaning that various verses are pulled from the text and cobbled together. It is a very specific use of Scripture done in and by the Church – reordering the canonical texts for a specific effect. The two readings, one from the Prophet Micah and one from the Prophet Isaiah are below, in the order they are read in Vespers. I won’t offer any comment, but wish you a blessed Feast of Mid-Pentecost.
First Reading: Micah 4:2-3, 5; 6:2-5, 8; 5:4,5
[4:2] Many nations shall come and say: “Come, let us go up to the mountain of the LORD, to the house of the God of Jacob; that he may teach us his ways and that we may walk in his paths.” For out of Zion shall go forth instruction, and the word of the LORD from Jerusalem.  He shall judge between many peoples, and shall arbitrate between strong nations far away; they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war any more;  For all the peoples walk, each in the name of its god, but we will walk in the name of the LORD our God forever and ever.
[6:2] Hear, you mountains, the controversy of the LORD, and you enduring foundations of the earth; for the LORD has a controversy with his people, and he will contend with Israel.  “O my people, what have I done to you? In what have I wearied you? Answer me!  For I brought you up from the land of Egypt, and redeemed you from the house of slavery; and I sent before you Moses, Aaron, and Miriam. …  He has told you, O mortal, what is good; and what does the LORD require of you but to do justice, and to love kindness, and to walk humbly with your God?
[5:4] And he shall stand and feed his flock in the strength of the LORD, in the majesty of the name of the LORD his God. And they shall live secure, for now he shall be great to the ends of the earth;  and he shall be the one of peace.
Second Reading: Isaiah 55:1, 12:3-4; 55:2-13 (NRSV)
[55:1] Ho, everyone who thirsts, come to the waters; and you that have no money, come, buy and eat! Come, buy wine and milk without money and without price.
[12:3] With joy you will draw water from the wells of salvation.  And you will say in that day: Give thanks to the LORD, call on his name; make known his deeds among the nations; proclaim that his name is exalted.
[55:2] Why do you spend your money for that which is not bread, and your labor for that which does not satisfy? Listen carefully to me, and eat what is good, and delight yourselves in rich food.  Incline your ear, and come to me; listen, so that you may live. I will make with you an everlasting covenant, my steadfast, sure love for David.  See, I made him a witness to the peoples, a leader and commander for the peoples.  See, you shall call nations that you do not know, and nations that do not know you shall run to you, because of the LORD your God, the Holy One of Israel, for he has glorified you.  Seek the LORD while he may be found, call upon him while he is near;  let the wicked forsake their way, and the unrighteous their thoughts; let them return to the LORD, that he may have mercy on them, and to our God, for he will abundantly pardon.  For my thoughts are not your thoughts, nor are your ways my ways, says the LORD.  For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts.  For as the rain and the snow come down from heaven, and do not return there until they have watered the earth, making it bring forth and sprout, giving seed to the sower and bread to the eater,  so shall my word be that goes out from my mouth; it shall not return to me empty, but it shall accomplish that which I purpose, and succeed in the thing for which I sent it.  For you shall go out in joy, and be led back in peace; the mountains and the hills before you shall burst into song, and all the trees of the field shall clap their hands.  Instead of the thorn shall come up the cypress; instead of the brier shall come up the myrtle; and it shall be to the LORD for a memorial, for an everlasting sign that shall not be cut off.
