Connected Through Trust

The Alter Rebbe (Torah Or Beshalach 63:4 and other places) says by way of derash on the possuk of הנה אלקינו זה קִוִּ֥ינוּ ל֖וֹ וְיוֹשִׁיעֵ֑נוּ זֶ֤ה י״י֙ קִוִּ֣ינוּ ל֔וֹ נָגִ֥ילָה וְנִשְׂמְחָ֖ה בִּישׁוּעָתֽוֹ that the word קוינו, we trusted in, can be related to the word קוין, a line, a rod, a line of connectivity.  Through our avodah of connecting Hashem to the world, that will allow us to relish with a connection to Hashem.  Possibly, through this idea we can explain deruch derush as well the possuk קַוֵּ֗ה אֶל⁠־י֫״י֥ חֲ֭זַק וְיַאֲמֵ֣ץ לִבֶּ֑ךָ וְ֝קַוֵּ֗ה אֶל⁠־י״יֽ.  What's the repetition of קוה אל ה?  The first קוה is trust in Hashem, חֲ֭זַק וְיַאֲמֵ֣ץ לִבֶּ֑ךָ and then וקוה אל ה, you will become connected to Hashem.
