Or "salvation" (KJV, NIV, NRSV).
The words "in him" are supplied in the translation for clarification.
The Hebrew text has, "for my strength and protection [is] the Yahweh, the Yahweh (Heb "Yah, Yahweh)." The word יְהוָה (yehvah) is probably dittographic or explanatory here (note that the short form of the name [יָהּ, yah] precedes, and that the graphically similar וַיְהִי [vayéhi] follows). Exod 15:2LEB, the passage from which the words of v. 2b are taken, has only יָהּ. The word זִמְרָת (zimrat) is traditionally understood as meaning "song," in which case one might translate, "for the Yahweh gives me strength and joy" (i.e., a reason to sing); note that in v. 5 the verb זָמַר (zamar, "sing") appears. Many recent commentators, however, have argued that the noun is here instead a homonym, meaning "protection" or "strength." See HALOT 274 s.v. III *זמר.
