Isaiah 50:4 describes a servant of God who has been given the ability to speak a word that strengthens people who are worn out and discouraged. The verse says this ability comes from God, who also trains the servant to listen to him each morning before speaking. The speaker is the prophet, writing in the voice of God’s faithful servant, and the words are addressed to anyone who is weary, first of all the exiles who had lost hope in Jerusalem.
The Lord the LORD has given me the tongue of those who are taught, that I may know how to sustain with words him who is weary. He wakens morning by morning, he wakens my ear to hear as those who are taught.

What Isaiah 50:4 Means
The phrase “the tongue of those who are taught” points to a skill of speech that is learned rather than natural. A teacher instructs a student, and the student then knows what to say at the right time. Here the servant is said to have received this kind of instruction directly from the Lord, so that his words are not his own guesses but fit the need in front of him.
The purpose of that speech is stated plainly: “to sustain with words him who is weary.” The Hebrew word for sustain carries the sense of upholding someone or helping them keep going, like lifting a tired traveler to his feet. The verse does not promise that every hard circumstance will disappear. It promises that God will equip a person to speak life into someone who is exhausted.
The second half of the verse shows where that equipping begins. God “wakens my ear” morning by morning, so the servant’s listening comes before his speaking. The verse does not claim that a believer will always know the right words in advance, but it does describe a pattern of daily attentiveness to God as the source of whatever comfort is offered to others.
The Context of Isaiah 50:4
Isaiah 50 belongs to the second major section of the book of Isaiah, often called the book of comfort, which speaks to Judah during or just before the Babylonian exile. The prophet is traditionally identified as Isaiah son of Amoz, and his first audience was a people who felt abandoned by God and sold off because of their sins. In the verses just before this one, the LORD asks where the certificate of divorce is and insists that he has not forgotten his people or lost the power to save them.
The verses that follow in 50:5 to 7 show the servant facing violence and shame while remaining steady because the Lord helps him. Read in that setting, the tongue of the taught is not a gift for an easy ministry. It is a gift given to someone who will himself be struck and spat upon, which explains why the words of comfort carry such weight in the passage.

Isaiah 40:29
He gives power to the weak. He increases the strength of him who has no might.

This verse from earlier in Isaiah also speaks of God giving strength to the weary and power to the faint. Reading it alongside Isaiah 50:4 shows that the prophet consistently ties God’s care for the tired to his own active provision.
A Short Prayer From Isaiah 50:4
Lord, you wake me each morning and open my ear to hear what you are saying. Teach me to listen before I speak, so that my words to tired people come from your instruction rather than my own hurry. Give me patience with those who are worn down, and help me to lift them up with the truth of your faithfulness. Keep my ear open to you today, and let my tongue be a means of strength for someone who needs it. Amen.
