מדרש אויף תהילים 26:6

(Ib. b) Ulla said: "Whoever reads the Sh'm'a without wearing Tephilin, is like one who testifies falsely against himself." R. Chiya b. Abba in the name of R. Jochanan says: "It is as if he had offered a burnt offering without the meal offering, or a sacrifice without the accompanying wine offering." R. Jochanan said: "He who desires to take upon himself the yoke of the Heavenly Kingdom perfectly (Fol. 15a) must first ease himself, wash his hands, lay Tephilin, read the Sh'm'a and pray [the Eighteen Benedictions]: this is the perfect acknowledgment of the Heavenly Kingdom." R. Chiya b. Abba said: "Whoever eases himself, washes his hands, lays Tephilin, reads the Sh'm'a and prays [the Eighteen Benedictions], is considered as having built an altar and offered a sacrifice upon it, for it is said (Ps. 26. 6.) I will wash in purity mine hands, and I will compass thy altar. O Lord." Raba said unto him (R. Chiya b. Abba): "Does not the master consider the washing of the hands just as if he bathed? For it is written I will wash in purify [which indicates for the whole body], and it is not written I wash my hands."

I will wash my hands with cleanliness, so that it is through legitimate means and not through theft, as it is taught (Mishnah Sukkah 3:11), "A stolen or dried-out palm branch is invalid." I will be free of violence and theft, so that I do not become a prosecutor turned into a defendant. And afterwards, "I will surround Your altar, O Lord" (Psalms 26:6). As it is taught, "Every day the altar is surrounded once and they say (Psalms 118:25), 'Please, O Lord, save us now!'"...

Another matter: “You shall take for you on the first day” – that is what is written: “I wash my hands in purity” (Psalms 26:6) – with a transaction and not with robbery, as we learned there: A lulav that was stolen or that is dry is unfit; of an ashera tree or from a city incited to idolatry, is unfit.¹⁶Mishna Sukka 3:1. “I circle Your altar, Lord,” (Psalms 26:6) – as we learned there: Each day they would circle the altar one time and say: “Lord, please save us” (Psalms 118:25), Lord, please save us. Rabbi Yehuda says: Ani vaho,¹⁷This is part of God’s seventy-two letter name and has the same numerical value as please Lord [ana followed by the Tetragrammaton]. please save us. And on that day,¹⁸The seventh day of Sukkot. they would circle the altar seven times.¹⁹Mishna Sukka 4:5.
“Proclaiming thankfulness” (Psalms 26:7) – these are the offerings. “Relating all Your wonders” (Psalms 26:7) – Rabbi Avin said: This is Hallel; it contains [thanks] for the past, it contains [thanks] for the future, it contains [thanks] for these generations, it contains [thanks] for the messianic era, and it contains [thanks] for the days of Gog and Magog. “When Israel departed from Egypt” (Psalms 114:1) – for the past; “not for us, Lord” (Psalms 115:1) – for these generations; “I love that the Lord hears [my voice and my supplications]” (Psalms 116:1) – for the messianic era. “All the nations surrounded me” (Psalms 118:10) – for the days of Gog and Magog; “You are my God and I will thank You; my God, and I will exalt You” (Psalms 118:28) – for the future.
