Add full Gospel pericopes to post-Epiphany through Palm Sunday Matins readings

Same gap as the Advent/Christmas sweep: Nocturn 3's patristic homily
appeared with no Gospel pericope before it. Authors the full text for
post-epiphany-1 through -6, septuagesima/sexagesima/quinquagesima,
lent-1 through -4, passion-sunday, and palm-sunday.

Palm Sunday needed a different source than the rest: its Missale
[Evangelium] tag is the Passion narrative (Matt 26-27) proclaimed at
Mass, not the entry-into-Jerusalem pericope (Matt 21:1-9) its own
Nocturn 3 homily is actually about — that shorter Gospel is instead
read at the Blessing of Palms, sourced from there.

Proptérea vos non audítis, quia ex Deo non estis. Respondérunt ergo Judǽi et dixérunt ei: Nonne bene dícimus nos, quia Samaritánus es tu, et dæmónium habes? Respóndit Jesus: Ego dæmónium non hábeo, sed honorífico Patrem meum, et vos inhonorástis me. Ego autem non quæro glóriam meam: est, qui quærat et júdicet. Amen, amen, dico vobis: si quis sermónem meum serváverit, mortem non vidébit in ætérnum. Dixérunt ergo Judǽi: Nunc cognóvimus, quia dæmónium habes. Abraham mórtuus est et Prophétæ; et tu dicis: Si quis sermónem meum serváverit, non gustábit mortem in ætérnum. Numquid tu major es patre nostro Abraham, qui mórtuus est? et Prophétæ mórtui sunt. Quem teípsum facis? Respóndit Jesus: Si ego glorífico meípsum, glória mea nihil est: est Pater meus, qui gloríficat me, quem vos dícitis, quia Deus vester est, et non cognovístis eum: ego autem novi eum: et si díxero, quia non scio eum, ero símilis vobis, mendax. Sed scio eum et sermónem ejus servo. Abraham pater vester exsultávit, ut vidéret diem meum: vidit, et gavísus est. Dixérunt ergo Judǽi ad eum: Quinquagínta annos nondum habes, et Abraham vidísti? Dixit eis Jesus: Amen, amen, dico vobis, ántequam Abraham fíeret, ego sum. Tulérunt ergo lápides, ut jácerent in eum: Jesus autem abscóndit se, et exívit de templo.

+        At that time, Jesus said to the crowds of the Jews: Which of you can convict Me of sin? If I speak the truth, why do you not believe Me? He who is of God hears the words of God. The reason why you do not hear is that you are not of God. The Jews therefore in answer said to Him, Are we not right in saying that You are a Samaritan, and have a devil? Jesus answered, I have not a devil, but I honor My Father, and you dishonor Me. Yet, I do not seek My own glory; there is One Who seeks and Who judges. Amen, amen, I say to you, if anyone keep My word, he will never see death. The Jews therefore said, Now we know that You have a devil. Abraham is dead, and the prophets, and You say, 'If anyone keep My word he will never taste death.' Are You greater than our father Abraham, who is dead? And the prophets are dead. Whom do You make Yourself? Jesus answered, If I glorify Myself, My glory is nothing. It is My Father Who glorifies Me, of Whom you say that He is your God. And you do not know Him, but I know Him. And if I say that I do not know Him, I shall be like you, a liar. But I know Him, and I keep His word. Abraham your father rejoiced that he was to see My day. He saw it and was glad. The Jews therefore said to Him, You are not yet fifty years old, and have You seen Abraham? Jesus said to them, Amen, amen, I say to you, before Abraham came to be, I am. They therefore took up stones to cast at Him; but Jesus hid Himself, and went out from the temple.
