God chose a place for Israel to worship Him.

“But to the place which Yahweh your God shall choose out of all your tribes, to put his name there, even to his habitation shall you seek, and there you shall come;”
Deut 12:5 WEB

Then when God made a choice, Israel was obligated to perform all of their formal worship in that place.

“Only your holy things which you have, and your vows, you shall take, and go to the place which Yahweh shall choose:”
Deut 12:26 WEB

Also God has the right to choose who will be allowed
to approach Him for worship.

“and he spoke to Korah and to all his company, saying, In the morning Yahweh will show who are his, and who is holy, and will cause him to come near to him: even him whom he shall choose will he cause to come near to him.”
Num 16:5 WEB

We might compare it to our being able to choose who will come into our house to visit with us, so God has the right and does choose who can approach Him. In the test that followed in Numers 16, the presumptuous Korah was rejected as a priest, and he and all his house then entered Sheol alive, for their trying to push their choices on God!

And chose a special family for His Christ.

“Moreover he rejected the tent of Joseph,
And didn’t choose the tribe of Ephraim,
68 But chose the tribe of Judah,
Mount Zion which he loved.”
Psa 78:67-68 WEB

He can do that. If we can make decisions, God surely can.

“He also chose David his servant,
And took him from the sheepfolds;”
Psa 78:70 WEB

Then from that family Yahweh will bring His special One, His Messiah (Hebrew), His Christ (Greek).

“Behold, my servant, whom I uphold; my chosen, in whom my soul delights: I have put my Spirit on him; he will bring forth justice to the Gentiles.”
Isa 42:1 WEB

And of course, He did.

At a time, a still future time, God can “the second time recover” the Jews.

Of course the first time that God recovered the Jews from “Assyria, and from Egypt, and from Pathros, and from Cush, and from Elam, and from Shinar, and from Hamath,” was in the time of Ezra of Nehemiah. However, before even that first time happened, Isaiah foretold that God would recover the Jews a second time!

“It shall happen in that day, that the Lord will set his hand again the second time to recover the remnant of his people, who shall remain, from Assyria, and from Egypt, and from Pathros, and from Cush, and from Elam, and from Shinar, and from Hamath, and from the islands of the sea.”
Isa 11:11 WEB

He can do that, He can decide that, and perform whatever He wishes.

And God choses the time when He will judge
the heavens and the earth.

“When I choose the appointed time,
I will judge blamelessly.”
Psa 75:2 WEB

God makes choices.
