Pastor Robert Walker delivered his teaching on the threshold covenant during the Feast of Tabernacles in 2015. However, a request came up from one of our members, who wanted to hear it again.
We had it only in the form of audio and the audio quality is not 100% perfect, but the message comes through. The message is based on Psalm 50.
The occasion was a Sabbath gathering (in West Road, Kingston) of all the First Congregation of Yahweh groups.
Psalms 50:1 (KJV)
[50:1] (A Psalm of Asaph.) The mighty Elohim, even YHWH, hath spoken, and called the earth from the rising of the sun unto the going down thereof.
 Out of Zion, the perfection of beauty, Elohim hath shined.
 Our Elohim shall come, and shall not keep silence: a fire shall devour before him, and it shall be very tempestuous round about him.
 He shall call to the heavens from above, and to the earth, that he may judge his people.
 Gather my saints together unto me; those that have made a covenant with me by sacrifice.
 And the heavens shall declare his righteousness: for Elohim is judge himself. Selah.
 Hear, O my people, and I will speak; O Israel, and I will testify against thee: I am Elohim, even thy Elohim.
 I will not reprove thee for thy sacrifices or thy burnt offerings, to have been continually before me.
 I will take no bullock out of thy house, nor he goats out of thy folds.
 For every beast of the forest is mine, and the cattle upon a thousand hills.
 I know all the fowls of the mountains: and the wild beasts of the field are mine.
 If I were hungry, I would not tell thee: for the world is mine, and the fulness thereof.
 Will I eat the flesh of bulls, or drink the blood of goats?
 Offer unto Elohim thanksgiving; and pay thy vows unto the most High:
 And call upon me in the day of trouble: I will deliver thee, and thou shalt glorify me.
 But unto the wicked Elohim saith, What hast thou to do to declare my statutes, or that thou shouldest take my covenant in thy mouth?
 Seeing thou hatest instruction, and castest my words behind thee.
 When thou sawest a thief, then thou consentedst with him, and hast been partaker with adulterers.
 Thou givest thy mouth to evil, and thy tongue frameth deceit.
 Thou sittest and speakest against thy brother; thou slanderest thine own mother's son.
 These things hast thou done, and I kept silence; thou thoughtest that I was altogether such an one as thyself: but I will reprove thee, and set them in order before thine eyes.
 Now consider this, ye that forget Elohim, lest I tear you in pieces, and there be none to deliver.
 Whoso offereth praise glorifieth me: and to him that ordereth his conversation aright will I shew the salvation of Elohim.
