Albert Barnes Commentary Psalms 119:26

"I declared my ways, and thou answeredst me: Teach me thy statutes." — Psalms 119:26 (ASV)

I have declared my ways - That is, I have declared or recounted them to you. I have made mention of my cares, troubles, anxieties, purposes. I have laid them all before you, reserving or keeping back nothing.

And thou heardest me - You answered me. It is only when we declare all our ways before God that we can hope he will hear us.

It is right and proper that we should go before God with all our cares and troubles. There is nothing that gives us anxiety of which we may not speak to him, however trivial it may seem to be—even as a child speaks to a mother of the smallest matter that troubles him. When this is done, we may be assured that God will not turn away from us or disregard our cry.

“I told him all my secret grief;
My secret groaning reached his ears;
He gave my inward pains relief,
And calmed the tumult of my fears.”

Teach me thy statutes - Make known to me your will. Acquaint me with what you would have me to do. See Psalm 119:12.
