Yes it does, with two Hebrew words.
Our God, Elohenu (אֱלֹהֵינוּ), is a masculine plural construct noun.
One, Echad (אֶחָד), is a singular word but is often used to describe a single thing which has more than one part.
More about this, in the next full post, coming soon.
Hear, O Israel; The Lord our God is one Lord
שְׁמַע יִשְׂרָאֵל יְהוָֹה אֱלֹהֵינוּ יְהוָֹה אֶחָד
(Bold added by author to help the non-Hebrew reader more easily see the two key words discussed in this post).
