Ephraim will turn back to Elohim in repentance.

Jer 31:6-14 “For there shall be a day when watchmen On the hills of Ephraim shall call out, ‘Arise, and let us go up to Zion, To the LORD our God.’” 7For thus says the LORD, “Sing aloud with gladness for Jacob, And shout among the chiefs of the nations; Proclaim, give praise, and say, ‘O LORD, save Thy people, The remnant of Israel.’ 8“Behold, I am bringing them from the north country, And I will gather them from the remote parts of the earth, Among them the blind and the lame, The woman with child and she who is in labor with child, together; A great company, they shall return here. 9“With weeping they shall come, And by supplication I will lead them; I will make them walk by streams of waters, On a straight path in which they shall not stumble; For I am a father to Israel, And Ephraim is My first-born.” 10Hear the word of the LORD, O nations, And declare in the coastlands afar off, And say, “He who scattered Israel will gather him, And keep him as a shepherd keeps his flock.” 11For the LORD has ransomed Jacob, And redeemed him from the hand of him who was stronger than he. 12“And they shall come and shout for joy on the height of Zion, And they shall be radiant over the bounty of the LORD— Over the grain, and the new wine, and the oil, And over the young of the flock and the herd; And their life shall be like a watered garden, And they shall never languish again. 13“Then the virgin shall rejoice in the dance, And the young men and the old, together, For I will turn their mourning into joy, And will comfort them, and give them joy for their sorrow. 14“And I will fill the soul of the priests with abundance, And My people shall be satisfied with My goodness,” declares the LORD.
Luke 15:22
"But the father said to his slaves, 'Quickly bring out the best robe and put it on him, and put a ring on his hand and sandals on his feet;

Luke 15:23
and bring the fattened calf, kill it, and let us eat and be merry;

Luke 15:24
for this son of mine was dead, and has come to life again; he was lost, and has been found.' And they began to be merry.

Ephraim is the lost son who was dead in his trespasses and sins.

Romans 6:11-13 Even so consider yourselves to be dead to sin, but alive to God in Christ Jesus. 12Therefore do not let sin reign in your mortal body that you should obey its lusts, 13and do not go on presenting the members of your body to sin as instruments of unrighteousness; but present yourselves to God as those alive from the dead, and your members as instruments of righteousness to God.

He has returned and the Father is throwing a feast in celebration.

Isaiah 25:6-9 And the LORD of hosts will prepare a lavish banquet for all peoples on this mountain; A banquet of aged wine, choice pieces with marrow, And refined, aged wine. 7And on this mountain He will swallow up the covering which is over all peoples, Even the veil which is stretched over all nations. 8He will swallow up death for all time, And the Lord GOD will wipe tears away from all faces, And He will remove the reproach of His people from all the earth; For the LORD has spoken. 9And it will be said in that day, “Behold, this is our God for whom we have waited that He might save us. This is the LORD for whom we have waited; Let us rejoice and be glad in His salvation.”

Rev. 19:7-9 And the appearance of the locusts was like horses prepared for battle; and on their heads, as it were, crowns like gold, and their faces were like the faces of men. 8And they had hair like the hair of women, and their teeth were like the teeth of lions. 9And they had breastplates like breastplates of iron; and the sound of their wings was like the sound of chariots, of many horses rushing to battle.
