Psalm 63:3

New English Translation

³Because^[a] experiencing^[b] your loyal love is better than life itself,
my lips will praise you.

Psalm 63:3 tn This line is understood as giving the basis for the praise promised in the following line. Another option is to take the Hebrew particle כִּי (ki) as asseverative/emphasizing, “Indeed, your loyal love is better” (cf. NEB, which leaves the particle untranslated).
Psalm 63:3 tn The word “experiencing” is supplied in the translation for clarification. The psalmist does not speak here of divine loyal love in some abstract sense, but of loyal love revealed and experienced.
