Psalms 105:4

4. And his strength “Strength,” here, is sometimes understood figuratively of the sanctuary, as in Psalms 78:61. Thus, to seek God’s “strength” is “to be earnest and constant in attending upon the public worship of Jehovah in the place where his ark, the symbol of his ‘strength,’ is deposited.” French and Skinner. But it is better to take it as in the English text. The “strength” of God was the refuge and defense of his people. See Psalms 27:1; Psalms 29:11; Psalms 68:34-35. It is parallel to seek his face that is his favour, in the next member.
